*1. The applicable load current depends on the ambient temperature. For details, refer to Load Current vs. Ambient Temperature in Engineering

Data on page 1235.

*2. Applicable Load

Use the following formula to calculate the maximum total capacity of a heater load for a three-phase balanced load with delta connections.

Maximum load capacity = Load current × Load voltage × √3

Example: 15 A × 200 V × √3 = 5,196 W ≅ 5.1 kW

Heat Sink Area vs. Load Current (40°C and 80°C)

G3PE-225B-3H G3PE-525B-3H

Note: The heat sink area is the combined

area of all surfaces of the heat sink

that radiate heat.

For the G3PE-525B-3H, when a

current of 18 A flows through the SSR

at 40°C, the graph shows that a heat

sink area of about 2,500 cm2 would

be required. Therefore, if the heat

sink is square, one side of an

aluminum plate in the heat sink must

be 36 cm or longer (√2,500 (cm2)/2 =

36 cm (rounded to a whole number)).

Safety Precautions for All G3PE Models

For common precautions, refer to Safety Precautions for All Solid-state Relays on page 1191.

Minor electrical shock may occasionally occur.

Do not touch the G3PE terminal section (i.e., current-

carrying parts) while the power is being supplied.

Also, always attach the cover terminal.

The G3PE may rupture if short-circuit current flows.

As protection against accidents due to short-

circuiting, be sure to install protective devices, such

as fuses and no-fuse breakers, on the power supply

side.

Minor electrical shock may occasionally occur.

Do not touch the main circuit terminals on the G3PE

immediately after the power supply has been turned

OFF. Shock may result due to the electrical charge

stored in the built-in snubber circuit.

Minor burns may occasionally occur.

Do not touch the G3PE or the heat sink while the

power is being supplied or immediately after the

power supply has been turned OFF. The G3PE and

heat sink become extremely hot.

OMRON constantly strives to improve quality and reliability.

SSRs, however, use semiconductors, and semiconductors may

commonly malfunction or fail. In particular, it may not be possible to

ensure safety if the SSRs are used outside the rated ranges.

Therefore, always use the SSRs within the ratings. When using an

SSR, always design the system to ensure safety and prevent human

accidents, fires, and social harm in the event of SSR failure. System

design must include measures such as system redundancy,

measures to prevent fires from spreading, and designs to prevent

malfunction.

Transport

Do not transport the G3PE under the following conditions.

Doing so may result in damage, malfunction, or deterioration of

performance characteristics.

•Conditions in which the G3PE may be subject to water.

•Conditions in which the G3PE may be subject to high temperature

or high humidity.

•Conditions in which the G3PE is not packaged.

Operating and Storage Environments

Do not use or store the G3PE in the following locations. Doing so may

result in damage, malfunction, or deterioration of performance

characteristics.

•Locations subject to rainwater or water splashes.

•Locations subject to exposure to water, oil, or chemicals.

•Locations subject to high temperature or high humidity.

•Do not store in locations subject to ambient storage temperatures

outside the range −30 to 100°C.

•Do not use in locations subject to relative humidity outside the

range 45% to 85%.

•Locations subject to corrosive gases.

•Locations subject to dust (especially iron dust) or salts.

•Locations subject to direct sunlight.

•Locations subject to shock or vibration.

Installation and Handling

•Do not block the movement of the air surrounding the G3PE or heat

sink. Abnormal heating of the G3PE may result in shorting failures

of the output elements or burn damage.

•Do not use the G3PE if the heat radiation fins have been bent by

being dropped. Doing so may result in malfunction due to a

reduction in the heat radiation performance.

•Do not handle the G3PE with oily or dusty (especially iron dust)

hands. Doing so may result in malfunction.

•Attach a heat sink or radiator when using an SSR. Not doing so

may result in malfunction due to a reduction in the heat radiation

performance.

Installation and Mounting

•Mount the G3PE in the specified direction. Otherwise excessive

heat generated by the G3PE may cause short-circuit failures of the

output elements or burn damage.

•Make sure that there is no excess ambient temperature rise due to

the heat generation of the G3PE. If the G3PE is mounted inside a

panel, install a fan so that the interior of the panel is fully ventilated.

•Make sure the DIN track is securely mounted. Otherwise, the

G3PE may fall.

•When mounting the heat sink, do not allow any foreign matter

between the heat sink and the mounting surface. Foreign matter

may cause malfunction due to a reduction in the heat radiation

performance.

•If the G3PE is mounted directly in a control panel, use aluminum,

steel plating, or similar material with a low heat resistance as a

substitute for a heat sink. Using the G3PE mounted in wood or

other material with a high heat resistance may result in fire or

burning due to heat generated by the G3PE.

Installation and Wiring

•Use wires that are suited to the load current. Otherwise, excessive

heat generated by the wires may cause burning.

•Do not use wires with a damaged outer covering.

Otherwise, it may result in electric shock or ground leakage.

•Do not wire any wiring in the same duct or conduit as power or

high-tension lines. Otherwise, inductive noise may damage the

G3PE or cause it to malfunction.

•When tightening terminal screws, prevent any non-conducting

material from becoming caught between the screws and the

tightening surface. Otherwise, excessive heat generated by the

terminal may cause burning.

•Do not use the G3PE with loose terminal screws. Otherwise,

excessive heat generated by the wire may cause burning.

•For the G3PE models with a carry current of 35 A or larger, use M5

crimp terminals that are an appropriate size for the diameter of the

wire.

•Always turn OFF the power supply before performing wiring. Not

doing so may cause electrical shock.

Installation and Usage

•Select a load within the rated values. Not doing so may result in

malfunction, failure, or burning.

•Select a power supply within the rated frequencies. Not doing so

may result in malfunction, failure, or burning.

•If a surge voltage is applied to the load of the Contactor, a surge

bypass(*) will function to trigger the output element. The G3PE

therefore cannot be used for motor loads. Doing so may result in

load motor malfunction.

*Surge Bypass

This circuit protects the output circuit from being destroyed. This

suppresses the surge energy applied inside the SSR in comparison

with a varistor for the main circuit protection. By alleviating electrical

stress on the electronic components of the SSR's output circuit,

failure and destruction due to surge voltage are suppressed.

Reference value: Surge dielectric strength of 30 kV min.

(Test conditions: 1.2

s standard voltage waveform, peak voltage

of 30 kV, repeated 50 times according to JIS C5442)

CAUTION

Precautions for Safe Use

G3PE

The SSR in operation may cause an unexpected accident.

Therefore it is necessary to test the SSR under the variety of

conditions that are possible. As for the characteristics of the SSR, it is

necessary to consider differences in characteristics between

individual SSRs.

The ratings in this catalog are tested values in a temperature range

between 15°C and 30°C, a relative humidity range between 25% and

85%, and an atmospheric pressure range between 86 and 106 kPa.

It will be necessary to provide the above conditions as well as the load

conditions if the user wants to confirm the ratings of specific SSRs.

Causes of Failure

•Do not drop the G3PE or subject it to abnormal vibration or shock

during transportation or mounting. Doing so may result in

deterioration of performance, malfunction, or failure.

•Tighten each terminal to the torque specified below. Improper

tightening may result in abnormal heat generation at the terminal,

which may cause burning.

•Do not supply overvoltage to the input circuits or output circuits.

Doing so may result in failure or burning.

•Do not use or store the G3PE in the following conditions. Doing so

may result in deterioration of performance.

•Locations subject to static electricity or noise

•Locations subject to strong electric or magnetic fields

•Locations subject to radioactivity

Mounting

•The G3PE is heavy. Firmly mount the DIN Track and secure both

ends with End Plates for DIN Track mounting models. When

mounting the G3PE directly to a panel, firmly secure it to the panel.

Screw diameter: M4

Tightening torque: 0.98 to 1.47 N·m

Note: Make sure that the load current is 50% of the rated load current

when the G3PE is mounted horizontally.

For details on close mounting, refer to the related information

under performance characteristics.

Mount the G3PE in a direction so that the markings read

naturally.

•The G3PE-2N/-3N (DIN Track mounting models) can be mounted

on the following TR35-15Fe (IEC 60715) DIN Tracks.

Wiring

•When using crimp terminals, refer to the terminal clearances

shown below.

•Make sure that all lead wires are thick enough for the current.

•For three-element and two-element models, the output terminal will

be charged even when the Relay is OFF. Touching the terminal

may result in electric shock. To isolate the Relay from the power

supply, install an appropriate circuit breaker between the power

supply and the Relay.

Always turn OFF the power supply before wiring the Unit.

•Terminal L2 and terminal T2 of a 2-element model are internally

connected to each other. Connect terminal L2 to the ground

terminal of the power supply.

If terminal L2 is connected to a terminal other than the ground

terminal, cover all the charged terminals, such as heater terminals,

to prevent electric shock and ground faults.

Fuses

•Use a quick-burning fuse on the output terminals to prevent

accidents due to short-circuiting. Use a fuse with equal or greater

performance than those given in the following table.

EMI

This is a Class A product (for industrial environments). In a domestic

environment, the G3PE may cause radio interference, in which case

the user may be required to take appropriate measures.

Noise and Surge Effects

If noise or an electrical surge occurs that exceeds the malfunction

withstand limit for the G3PE output circuit, the output will turn ON for

a maximum of one half cycle to absorb the noise or surge. Confirm

that turning the output ON for a half cycle will not cause a problem for

the device or system in which the G3PE is being used prior to actual

use. The G3PE malfunction withstand limit is shown below.

•Malfunction withstand limit (reference value): 500 V

Note: This value was measured under the following conditions.

Noise duration: 100 ns and 1 μs

Repetition period: 100 Hz

Noise application time: 3 min

Mounting Models with Externally Attached Heat Sinks

•Before attaching an external Heat Sink or Radiator to the Unit,

always apply silicone grease, such as Momentive Performance

Material’s YG6260 or Shin-Etsu Chemical’s G747, to the mounting

surface to enable proper heat radiation.

•Tighten the screws to the following torque to secure the Unit and

external Heat Sink or Radiator to enable proper heat dissipation.

Tightening torque: 2.0 N·m

Mounting to Control Panel

The G3PE is heavy. Firmly mount the DIN track and secure both ends

with End Plates for DIN-track-mounting models. When mounting the

G3PE directly to a panel, firmly secure it to the panel.

If the panel is airtight, heat from the SSR will build up inside, which

may reduce the current carry ability of the SSR or adversely affect

other electrical devices. Be sure to install ventilation holes on the top

and bottom of the panel.

Note: 1. If the air inlet or air outlet has a filter, clean the filter regularly

to prevent it from clogging to ensure an efficient flow of air.

2. Do not locate any objects around the air inlet or air outlet,

otherwise the objects may obstruct the proper ventilation of

the control panel.

3. A heat exchanger, if used, should be located in front of the

G3PE to ensure the efficiency of the heat exchanger.

G3PE Ambient Temperature

The rated current of the G3PE is measured at an ambient

temperature of 40°C.

The G3PE uses a semiconductor to switch the load. This causes the

temperature inside the control panel to increase due to heating

resulting from the flow of electrical current through the load. The

G3PE reliability can be increased by adding a ventilation fan to the

control panel to dispel this heat, thus lowering the ambient

temperature of the G3PE.

(Arrhenius's law suggests that life expectancy is doubled by each

10°C reduction in ambient temperature.)

Example: For 10 G3PE SSRs with load currents of 15 A,

0.23 × 10 = 2.3

Thus, 3 fans would be required.

Note: 1. Size of fans: 92 mm × 92 mm, Air volume: 0.7 m3/min,

Ambient temperature of control panel: 30°C

2. If there are other instruments that generate heat in the

control panel in addition to SSRs, more ventilation will be

required.

3. Ambient temperature: The temperature that will allow the

SSR to cool by convection or other means.

Solid State Relays Common Precautions

●For precautions on individual products, refer to "■Precautions" in individual product information.

Touching the charged section is likely to cause

electric shock. Do not touch the SSR terminal

section (the charged section) when the power

supply is ON. For SSRs with terminal covers, be

sure to attach the cover before use.

The SSR and heat sink will be hot and are likely to

cause burns. Do not touch the SSR or the heat sink

either while the power supply is ON, or

immediately after the power is turned OFF.

The internal snubber circuit is charged and will

cause electric shock. Do not touch the SSR load

terminal immediately after the power is turned OFF.

Electric shock is likely to result. Be sure to

conduct wiring with the power supply turned OFF.

SSRs may occasionally explode. Do not apply a

short-circuit current to the load side of an SSR.

To protect against short-circuit accidents, be sure

to install a protective device, such as a

quick-break fuse etc. on the power supply line.

OMRON constantly strives to improve quality and reliability. SSRs,

however, use semiconductors, and semiconductors may commonly

malfunction or fail. Short-circuit failures represent the main failure

mode and can result in an inability to shut OFF the load. Therefore,

for fail-safe operation of control circuits that use SSRs, do not use

circuits that shut OFF the load power supply only with an SSR, but

rather also use circuits with a contactor or breaker that shuts off the

load when the SSR fails. In particular, it may not be possible to

ensure safety if the SSRs are used outside the rated ranges.

Therefore, always use the SSRs within the ratings.

When using an SSR, always design the system to ensure safety

and prevent human accidents, fires, and social harm in the event

of SSR failure. System design must include measures such as

system redundancy, measures to prevent fires from spreading,

and designs to prevent malfunction.

1. Do not apply voltage or current in excess of the ratings to the

terminals of the SSR. Doing so may result in failure or burn

damage.

2. Heat Radiation

xBe careful with the increase in ambient temperature caused

by self-heating. Mount a fan etc. to provide a sufficient air

ventilation especially in case of internal mounting.

xMount the SSR following the specified mounting orientation.

The abnormal heat generation from the body may cause

output elements to short or may cause burning.

3. Perform correct wiring following the precautions below.

Improper wiring may lead to abnormal heating resulting in burn

damage to the SSR once the power is supplied.

xUse a suitable wire according to the load current. Otherwise

the abnormal heating of the wire may cause burning.

4. Operating Conditions

xDesignate the load within the rated range. Otherwise it may

result in faulty operation, malfunction, or burning.

xUse a power supply within the rated frequency range.

Otherwise it may result in faulty operation, malfunction, or

burning.

5. Do not transport the SSR under the following conditions.

Failure, malfunction, or deterioration of performance

characteristics may occur.

xConditions under which the SSR will be exposed to water

xHigh temperatures or high humidity

xWithout proper packing

6. Operating and Storage Environment

Do not use or store the SSR in the following environments.

Doing so may result in damage, malfunction, or deterioration

of performance characteristics.

CAUTION Safety Cautions

xDo not use or store in environments subject to exposure

to sunlight.

xDo not use in environments subject to temperatures

outside the range specified individually.

xDo not use in environments subject to relative humidity

outside the range of 45% to 85% RH, or in locations

subject to condensation as the result of severe changes

in temperature.

xDo not store in environments subject to temperatures

outside the range specified individually.

xDo not use or store in environments subject to corrosive

or flammable gases.

xDo not use or store in environments subject to dust, salt,

or iron dust, or in locations subject to salt damage.

xDo not use or store in environments subject to shock or

vibration.

xDo not use or store in environments subject to exposure

to water, oil, or chemicals, or in environments subject to

exposure to rain and water splashes.

xDo not use or store in environments subject to high

temperature or high humidity.

Solid State Relays Common Precautions

●Before Using SSR

1. The SSR in operation may cause an unexpected accident.

Therefore it is necessary to test the SSR under the variety of

conditions that are possible.

For example, as for the characteristics of the SSR, it is

necessary to consider differences in characteristics between

individual SSRs.

2. The ratings in this catalog are tested values in a temperature

range between 15°C and 30°C, a relative humidity range

between 25% and 85%, and an atmospheric pressure range

between 88 and 106 kPa. It will be necessary to provide the

above conditions as well as the load conditions if the user

wants to confirm the ratings of specific SSRs.

■Input Circuit

●Connecting to the Input Side

There is variation in the input impedance of SSRs. Therefore, do

not connect multiple inputs in series. Otherwise malfunction may

occur.

●Input Noise

SSRs need only a small amount of power to operate. This is why

the input terminals must shut out electrical noise as much as

possible. Noise applied to the input terminals may result in

malfunction. The following describes measures to be taken

against pulse noise and inductive noise.

1. Pulse Noise

A combination of capacitor and resistor can absorb pulse

noise effectively. The following is an example of a noise

absorption circuit with capacitor C and resistor R connected to

an SSR incorporating a photocoupler.

The value of R and C must be decided carefully. The value of

R must not be too large or the supply voltage (E) will not be

able to satisfy the required input voltage value. The larger the

value of C is, the longer the release time will be, due to the

time required for C to discharge electricity.

Note. For low-voltage models, sufficient voltage may not be applied to the

SSR because of the relationship between C, R, and the internal

impedance. When deciding on a value for R, check the input

impedance for the SSR.

2. Inductive Noise

Do not wire power lines alongside the input lines. Inductive

noise may cause the SSR to malfunction. If inductive noise is

imposed on the input terminals of the SSR, use the following

cables according to the type of inductive noise, and reduce the

noise level to less than the must release voltage of the SSR.

Twisted-pair wire: For electromagnetic noise

Shielded cable: For static noise

A filter consisting of a combination of capacitor and resistor will

effectively reduce noise generated from high-frequency

equipment.

●Input Conditions

1. Input Voltage Ripples

When there is a ripple in the input voltage, set the input

voltage so that the peak voltage is lower than the maximum

operating voltage and the root voltage is above the minimum

operating voltage.

2. Countermeasures for Leakage Current

When the SSR is powered by transistor output, the must

release voltage may be insufficient due to leakage current

while power is OFF. To counteract this, connect bleeder

resistance as shown in the diagram below and set the bleeder

resistance so that VR is half of the release voltage or less.

The bleeder resistance R can be obtained in the way shown

below.

E : Voltage applied at both ends of the bleeder resistance =

half of the release voltage of the SSR

IL: Leakage current of the transistor

I : Release voltage of SSR

The actual value of the release current is not given in the

datasheet and so when calculating the value of the bleeder

resistance, use the following formula.

For SSRs with constant-current input circuits, calculation is

performed at 0.1 mA.

The calculation for the G3M-202P DC24 is shown below as an

example.

Solid State Relays Common Precautions

3. ON/OFF Frequency

An SSR has delay times called the operating time and release

time. Loads, such as inductive loads, also have delay times

called the operating time and release time. These delays must

all be considered when determining the switching frequency.

4. Input impedance

In SSRs which have wide input voltages (such as G3CN and

G3TB), the input impedance varies according to the input

voltage and changes in the input current.

For semiconductor-driven SSRs, changes in voltage can

cause malfunction of the semiconductor, so be sure to check

by the actual device before usage.

See the following examples.

Input impedance (Example)

G3CN

■Output Circuit

●AC Switching SSR Output Noise and Surges

xIn case there is a large voltage surge in the AC current being

used by the SSR, the RC snubber circuit built into the SSR

between the SSR load terminals will not be sufficient to

suppress the surge, and the SSR transient peak element

voltage will be exceeded, causing overvoltage damage to the

SSR.

xOnly the following models have a built-in surge absorbing

varistor: G3NA, G3S, G3PA, G3NE, G3PH, G3DZ (some

models), G3RZ, and G3FM. When switching an inductive load

with any other models, be sure to take countermeasures

against surge, such as adding a surge absorbing element.

xIn the following example, a surge voltage absorbing element

has been added.

Select an element which meets the conditions in the following

table as the surge absorbing element.

●Output Connections

Do not connect SSR outputs in parallel. With SSRs, both sides of

the output will not turn ON at the same time, so the load current

cannot be increased by using parallel connections.

●DC Switching SSR Output Noise Surges

When an L load, such as a solenoid or electromagnetic valve, is

connected, a diode that prevents counter-electromotive force. If

the counter-electromotive force exceeds the withstand voltage of

the SSR output element, it could result in damage to the SSR

output element. To prevent this, insert the element parallel to the

load, as shown in the following diagram and table.

As an absorption element, the diode is the most effective at

suppressing the counter-electromotive force. The release time

for the solenoid or electromagnetic valve will, however, increase.

Be sure to check the circuit before use. To shorten the time,

connect a Zener diode and a regular diode in series. The release

time will be shortened at the same rate that the Zener voltage

(Vz) of the Zener diode is increased.

Talbe 1. Absorption Element Example

2. Selecting a Zener Diode

Note. When the Zener voltage is increased (Vz), the Zener diode capacity

(PRSM) is also increased.

●Selecting an SSR for Different Loads

The following provides examples of the inrush currents for

different loads.

AC Load and Inrush Current

1. Heater Load (Resistive Load)

A resistive load has no inrush current. The SSR is generally

used together with a pulse-voltage-output in temperature

controller for heater ON/OFF switching. When using an SSR

with the zero cross function, most generated noise is

suppressed. This type of load does not, however, include

all-metal and ceramic heaters. Since the resistance values at

normal temperatures of all-metal and ceramic heaters are low,

an overcurrent will occur in the SSR, causing damage. For

switching of all-metal and ceramic heaters, select a Power

Controller (G3PW, consult your OMRON representative) with a

long soft-start time, or a constant-current switch.

2. Lamp Load

A large inrush current flows through incandescent lamps,

halogen lamps, and similar devices (approx. 10 to 15 times

higher than the rated current). Select an SSR so that the peak

value of inrush current does not exceed half the inrush current

resistance of the SSR. Refer to “Repetitive” (indicated by the

dashed line) shown in the following figure. When a repetitive

inrush current of greater than half the inrush current resistance

is applied, the output element of the SSR may be damaged.

3. Motor Load

When a motor is started, an inrush current of 5 to 10 times the

rated current flows and the inrush current flows for a longer

time than for a lamp or transformer. In addition to measuring

the startup time of the motor or the inrush current during use,

ensure that the peak value of the inrush current is less than

half the inrush current resistance when selecting an SSR. The

SSR may be damaged by counterelectromotive force from the

motor. Be sure to install overcurrent protection for when the

SSR is turned OFF.

4. Transformer Load

When the SSR is switched ON, an energizing current of 10 to

20 times the rated current flows through the SSR for 10 to 500

ms. If there is no load in load side circuit, the energizing

current will reach the maximum value. Select an SSR so that

the energizing current does not exceed half the inrush current

resistance of the SSR.

5. Half-wave Rectifying Circuit

AC electromagnetic counters or solenoids have built-in diodes,

which act as half-wave rectifiers. For these types of loads, a

halfwave AC voltage does not reach the SSR output. For

SSRs with the zero cross function, this can cause them not to

turn ON. Two methods for counteracting this problem are

described below.

1. Connect a bleeder resistance with approximately 20% of the

SSR load current.

2. Use SSRs without the zero cross function.

6. Full-wave Rectified Loads

AC electromagnetic counters and solenoids have built-in

diodes, which act as full-wave rectifiers. The load current for

these types of loads has a rectangular wave pattern, as shown

in the following diagram.

Accordingly, AC SSRs use a triac (which turns OFF the

element only when the circuit current is 0 A) in the output

element. If the load current waveform is rectangular, it will

result in an SSR release error.

When switching ON and OFF a load whose waves are all

rectified, use Power MOS FET Relay.

-V-model SSRs: G3F-203SL-V, G3H-203SL-V

Power MOS FET Relay: G3DZ, G3RZ, G3FM

Note. Refer to your OMRON website for detailed specification of G3FM

models.

7. Small-capacity Loads

Even when there is no input signal to the SSR, there is a small

leakage current (IL) from the SSR output (LOAD). If this

leakage current is larger than the load release current, the

SSR may fail to release. Connect a bleeder resistance R in

parallel to increase the SSR switching current.

Solid State Relays Common Precautions

8. Inverter Load

Do not use an inverter-controlled power supply as the load

power supply for the SSR. Inverter-controlled waveforms

become rectangular, so the dV/dt ratio is extremely large and

the SSR may fail to release.

An inverter-controlled power supply may be used on the input

side provided the effective voltage is within the normal

operating voltage range of the SSR.

9. Capacitive Load

The supply voltage plus the charge voltage of the capacitor is

applied to both ends of the SSR when it is OFF. Therefore, use

an SSR model with an input voltage rating twice the size of the

supply voltage. Limit the charge current of the capacitor to less

than half the peak inrush current value allowed for the SSR.

10. SSR for DC Switching

Connection

With the SSR for DC switching, the load can be connected to

either negative (-) or positive (+) output terminal of the SSR.

Protective Component

Since the SSR does not incorporate an overvoltage absorption

component, be sure to connect an overvoltage absorption

component when using the SSR under an inductive load.

■Load Power Supply

1. Rectified Currents

If a DC load power supply is used for full-wave or half-wave

rectified AC currents, make sure that the peak load current does

not exceed the maximum usage load power supply of the SSR.

Otherwise, overvoltage will cause damage to the output element

of the SSR.

2. Operating Frequency for AC Load Power Supply

The operating frequency range for an AC load power supply is 47

to 63 Hz.

3. Low AC Voltage Loads

If the load power supply is used under a voltage below the

minimum operating load voltage of the SSR, the loss time of the

voltage applied to the load will become longer than that of the

SSR operating voltage range. See the following load example.

(The loss time is A < B.)

Before operating the SSR, make sure that this loss time will not

cause problems.

If the load voltage falls below the trigger voltage, the SSR will not

turn ON, so be sure to set the load voltage to 75 VAC min.

4. Phase-controlled AC Power Supplies

Phase-controlled power supply cannot be used.

■Operating and Storage Environments

1. Operating Ambient Temperature

The rated value for the ambient operating temperature of the

SSR is for when there is no heat build-up. For this reason, under

conditions where heat dissipation is not good due to poor

ventilation, and where heat may build up easily, the actual

temperature of the SSR may exceed the rated value resulting in

malfunction or burning.

When using the SSR, design the system to allow heat dissipation

sufficient to stay below the “●Load Current vs. Ambient

Temperature” characteristic curve. Note also that the ambient

temperature of the SSR may increase as a result of

environmental conditions (e.g., climate or air-conditioning) and

operating conditions (e.g., mounting in an airtight panel).

2. Transportation

When transporting the SSR, observe the following points. Not

doing so may result in damage, multifunction, or deterioration of

performance characteristics.

3. Vibration and Shock

Do not subject the SSR to excessive vibration or shock.

Otherwise the SSR may malfunction and internal components

may be damaged.

To prevent the SSR from abnormal vibration, do not install the

SSR in locations or by means that will subject it to vibration from

other devices, such as motors.

4. Solvents

Do not allow the SSR to come in contact with solvents, such as

thinners or gasoline. Doing so will dissolve the markings on the

SSR.

5. Oil

Do not allow the SSR terminal cover to come in contact with oil.

Doing so will cause the cover to crack and become cloudy.

ΔV/ΔT = dV/dt: voltage increase ratio The dV/dt ratio tends to infinity,

so the SSR will not turn OFF.

An inductance (L) load

as shown on the left.

Therefore, the loss is not as

This is because a high

voltage is already imposed on

the SSR when the input

current to the SSR drops to

zero and the SSR is turned

OFF.

Solid State Relays Common Precautions

■Actual Operation

1. Leakage Current

A leakage current flows through a snubber circuit in the SSR

even when there is no input. Therefore, always turn OFF the

input or load and check that it is safe before replacing or wiring

the SSR.

2. Cutting Terminals

Do not cut the terminals using an automated-cutter. Cutting the

terminals with devices such as an automated-cutter may

damage the internal components.

3. Deformed Terminals

Do not attempt to repair or use a terminal that has been

deformed. Otherwise excessive force will be applied to the SSR,

and it will lose its original performance capabilities.

4. Hold-down Clips

Exercise care when pulling or inserting the hold-down clips so

that their form is not distorted. Do not use a clip that has already

been deformed. Otherwise excessive force will be applied to the

SSR, causing it not to perform to its specification, and also it will

not have enough holding power, causing the SSR to be loose,

and resulting in damage to the contacts.

5. PCB SSR Soldering

xSSRs must be soldered at 260°C within five seconds. For

models, however, that conform to separate conditions, perform

soldering according to the specified requirements.

xUse a rosin-based non-corrosive flux that is compatible with

the material of the SSR.

6. Ultrasonic Cleaning

Do not perform ultrasonic cleaning. Performing ultrasonic

cleaning after the SSR base has been installed will cause

ultrasonic waves to resonate throughout the SSR internal

structure, thereby damaging the internal components.

■Safety Concept

1. Error Mode

The SSR is an optimum relay for high-frequency switching and

highspeed switching, but misuse or mishandling of the SSR may

damage the elements and cause other problems. The SSR

consists of semiconductor elements, and will break down if these

elements are damaged by surge voltage or overcurrent. Most

faults associated with the elements are short-circuit

malfunctions, whereby the load cannot be turned OFF.

Therefore, to provide a safety feature for a control circuit using an

SSR, design a circuit in which a contactor or circuit breaker on

the load power supply side will turn OFF the load when the SSR

causes an error. Do not design a circuit that turns OFF the load

power supply only with the SSR. For example, if the SSR causes

a half-wave error in a circuit in which an AC motor is connected

as a load, DC energizing may cause overcurrent to flow through

the motor, thus burning the motor. To prevent this from occurring,

design a circuit in which a circuit breaker stops overcurrent to the

motor.

2. Short-circuit Protection

A short-circuit current or an overcurrent flowing through the load

of the SSR will damage the output element of the SSR. Connect

a quick-break fuse in series with the load as a short-circuit

protection measure.

Design a circuit so that the protection coordination conditions for

the quick-break fuse satisfy the relationship between the SSR

surge resistance (IS), quick-break fuse current-limiting feature

(IF), and the load inrush current (IL), shown in the following chart.

3. Operation Indicator

The operation indicator turns ON when current flows through the

input circuit. It does not indicate that the output element is ON.

Solid State Relays Common Precautions

■HANDLING THE SSR

●Do Not Drop

The SSR is a high-precision component. Do not drop the SSR or

subject it to excessive vibration or shock regardless of whether

the SSR is mounted or not.

The maximum vibration and shock that an SSR can withstand

varies with the model. Refer to the relevant datasheet.

The SSR cannot maintain its full performance capability if the

SSR is dropped or subjected to excessive vibration or shock.

In addition, it may result in malfunction due to its damaged

internal components if the SSR is dropped or subjected to

excessive vibration or shock.

The impact of shock given to the SSR that is dropped varies

upon the case. For example, if a single SSR is dropped on a

plastic tile from a height of 10 cm, the SSR may receive a shock

of 1,000 m/s2 or more. (It depends on the floor material, the

angle of collision with the floor, and the dropping height.)

Handle the SSR models in stick packages with the same care

and keep them free from excessive vibration or shock.

●Terminal arrangement/Internal connections

1. BOTTOM VIEW

If the relay's terminals cannot be seen from above, as in this

example, a BOTTOM VIEW is shown.

2. Rotating direction to BOTTOM VIEW

The following shows the terminal rotated in the direction

indicated by the arrow, with the coil always on the left

(orientation mark on the left).

■PCB-mounting SSRs

1. Suitable PCBs

1 PCB Material

PCBs are classified into epoxy PCBs and phenol PCBs. The

following table lists the characteristics of these PCBs. Select

one, taking into account the application and cost. Epoxy PCBs

are recommended for SSR mounting in order to prevent the

solder from cracking.

2 PCB Thickness

The PCB may warp due to the size, mounting method, or

ambient operating temperature of the PCB or the weight of

components mounted to the PCB. Should warping occur, the

internal mechanism of the SSR on the PCB will be deformed

and the SSR may not provide its full capability. Determine the

thickness of the PCB by taking the material of the PCB into

consideration.

3 Terminal Hole and Land Diameters

Refer to the following table to select the terminal hole and land

diameters based on the SSR mounting dimensions. The land

diameter may be smaller if the land is processed with through-hole

plating.

2. Mounting Space

The ambient temperature around the sections where the SSR is

mounted must be within the permissible ambient operating

temperature. If two or more SSRs are mounted closely together,

the SSRs may radiate excessive heat. Therefore, make sure that

the SSRs are separated from one another at the specified

distance provided in the datasheet. If there is no such

specification, maintain a space that is as wide as a single SSR.

Provide adequate ventilation to the SSRs as shown in the

following diagram.

to any SSR.

Note 2. The space between the SSR and PCB may

be not be adequately cleaned with a

hydrocarbon or alcohol detergent.

Boiling or dip cleaning is possible for the SSR. Do

not perform ultrasonic cleaning or cut the

terminals, otherwise the internal parts of the SSR

voltage due to LC coupling. Be sure to use an SSR model with

a rated output voltage of at least twice the supply voltage.

For example, if the motor operates at a supply voltage of 100

VAC, the SSR must have an output voltage of 200 VAC or

higher.

Note 2. Make sure that there is a time lag of 30 ms or more to switch

over SW1 and SW2.

tion, abuse, misuse or inappropriate modification. Return of any Products by

Buyer must be approved in writing by Omron before shipment. Omron Compa-

nies shall not be liable for the suitability or unsuitability or the results from the

use of Products in combination with any electrical or electronic components,

circuits, system assemblies or any other materials or substances or environ-

ments. Any advice, recommendations or information given orally or in writing,

are not to be construed as an amendment or addition to the above warranty.

lished information.

14. Limitation on Liability; Etc. OMRON COMPANIES SHALL NOT BE LIABLE

FOR SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES,

LOSS OF PROFITS OR PRODUCTION OR COMMERCIAL LOSS IN ANY

WAY CONNECTED WITH THE PRODUCTS, WHETHER SUCH CLAIM IS

BASED IN CONTRACT, WARRANTY, NEGLIGENCE OR STRICT LIABILITY.

Further, in no event shall liability of Omron Companies exceed the individual

price of the Product on which liability is asserted.

15. Indemnities. Buyer shall indemnify and hold harmless Omron Companies and

their employees from and against all liabilities, losses, claims, costs and

expenses (including attorney's fees and expenses) related to any claim, inves-

tigation, litigation or proceeding (whether or not Omron is a party) which arises

or is alleged to arise from Buyer's acts or omissions under these Terms or in

any way with respect to the Products. Without limiting the foregoing, Buyer (at

its own expense) shall indemnify and hold harmless Omron and defend or set-

tle any action brought against such Companies to the extent based on a claim

that any Product made to Buyer specifications infringed intellectual property

rights of another party.

16. Property; Confidentiality. Any intellectual property in the Products is the exclu-

sive property of Omron Companies and Buyer shall not attempt to duplicate it

in any way without the written permission of Omron. Notwithstanding any

charges to Buyer for engineering or tooling, all engineering and tooling shall

remain the exclusive property of Omron. All information and materials supplied

by Omron to Buyer relating to the Products are confidential and proprietary,

and Buyer shall limit distribution thereof to its trusted employees and strictly

prevent disclosure to any third party.

17. Export Controls. Buyer shall comply with all applicable laws, regulations and

licenses regarding (i) export of products or information; (iii) sale of products to

“forbidden” or other proscribed persons; and (ii) disclosure to non-citizens of

regulated technology or information.

18. Miscellaneous. (a) Waiver. No failure or delay by Omron in exercising any right

and no course of dealing between Buyer and Omron shall operate as a waiver

of rights by Omron. (b) Assignment. Buyer may not assign its rights hereunder

without Omron's written consent. (c) Law. These Terms are governed by the

law of the jurisdiction of the home office of the Omron company from which

Buyer is purchasing the Products (without regard to conflict of law princi-

ples). (d) Amendment. These Terms constitute the entire agreement between

Buyer and Omron relating to the Products, and no provision may be changed

or waived unless in writing signed by the parties. (e) Severability

. If any provi-

sion hereof is rendered ineffective or invalid, such provision shall not invalidate

any other provision. (f) Setoff. Buyer shall have no right to set off any amounts

against the amount owing in respect of this invoice. (g) Definitions. As used

herein, “including” means “including without limitation”; and “Omron Compa-

nies” (or similar words) mean Omron Corporation and any direct or indirect

subsidiary or affiliate thereof.

Certain Precautions on Specifications and Use

1. Suitability of Use. Omron Companies shall not be responsible for conformity

with any standards, codes or regulations which apply to the combination of the

Product in the Buyer’s application or use of the Product. At Buyer’s request,

Omron will provide applicable third party certification documents identifying

ratings and limitations of use which apply to the Product. This information by

itself is not sufficient for a complete determination of the suitability of the Prod-

uct in combination with the end product, machine, system, or other application

or use. Buyer shall be solely responsible for determining appropriateness of

the particular Product with respect to Buyer’s application, product or system.

Buyer shall take application responsibility in all cases but the following is a

non-exhaustive list of applications for which particular attention must be given:

(i) Outdoor use, uses involving potential chemical contamination or electrical

interference, or conditions or uses not described in this document.

(ii) Use in consumer products or any use in significant quantities.

(iii) Energy control systems, combustion systems, railroad systems, aviation

systems, medical equipment, amusement machines, vehicles, safety equip-

ment, and installations subject to separate industry or government regulations.

(iv) Systems, machines and equipment that could present a risk to life or prop-

erty. Please know and observe all prohibitions of use applicable to this Prod-

uct.

NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS

RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT

ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO

ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-

ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE

OVERALL EQUIPMENT OR SYSTEM.

2. Programmable Products. Omron Companies shall not be responsible for the

user’s programming of a programmable Product, or any consequence thereof.

3. Performance Data. Data presented in Omron Company websites, catalogs

and other materials is provided as a guide for the user in determining suitabil-

ity and does not constitute a warranty. It may represent the result of Omron’s

test conditions, and the user must correlate it to actual application require-

ments. Actual performance is subject to the Omron’s Warranty and Limitations

of Liability.

4. Change in Specifications. Product specifications and accessories may be

changed at any time based on improvements and other reasons. It is our prac-

tice to change part numbers when published ratings or features are changed,

or when significant construction changes are made. However, some specifica-

tions of the Product may be changed without any notice. When in doubt, spe-

cial part numbers may be assigned to fix or establish key specifications for

your application. Please consult with your Omron’s representative at any time

to confirm actual specifications of purchased Product.

5. Errors and Omissions. Information presented by Omron Companies has been

checked and is believed to be accurate; however, no responsibility is assumed

for clerical, typographical or proofreading errors or omissions.
