■Ratings
Note: 1. DC ripple rate: 20% max. (A single-phase, full-wave-rectification power supply can be used).
2. Do not use an inverter output as the power supply. Refer to your OMRON website for details.
3. Models with 24-to-48-VAC or 12-to-48-VDC power supply have inrush current. Caution is thus required when turning ON and OFF power
to the Timer with a non-contact output from a device such as a sensor. (Models with an inrush current of approximately 50 mA and a 24-
VDC power supply are available (the H3CR-A-302 and H3CR-A8-302).)
For details, consult your OMRON sales representative.
4. The values are for when the terminals 2 and 7 and terminals 10 and 6 are short-circuited, and include the consumption current of the
input circuit.
5. Refer to your OMRON website when using the Timer together with a 2-wire AC proximity sensor.

Safety Precautions (H3CR-A)
Refer to Safety Precautions for All Timers.
Note: The following precautions apply to all H3CR-A models.
■Power Supplies
For the power supply of an input device of the H3CR-A use an
isolating transformer with the primary and secondary windings
mutually isolated and the secondary winding not grounded.
The H3CR-A’s power supply terminal 2 is a common terminal for
input signals to the Timer. Do not disconnect the wires on terminal 2,
otherwise the internal circuitry of the Timer will be damaged.
■Input/Output
Relationship between Input and Power
Supply Circuits (except for H3CR-A8E)
The H3CR-A (except for H3CR-A8E) uses transformerless power
supply. When connecting a relay or transistor as an external signal
input device, pay attention to the following points to prevent short-
circuiting due to a sneak current to the transformerless power supply.
If a relay or transistor is connected to two or more Timers, the input
terminals of those Timers must be wired properly so that they will not
differ in phase, otherwise the terminals will be short-circuited to one
another.
It is impossible to provide two independent power switches as shown
below regardless of whether or not the Timers are different in phase.

Relationship between Input and Power
Supply Circuits (H3CR-A@/-A@S)
An appropriate input is applied to the input signal terminals of the
H3CR-A@/-A@S when one of the input terminals is short-circuited
with the common terminal (terminal 2) for the input signals. Never
use terminal 10 as the common terminal for this purpose, otherwise
the internal circuit of the Timer will be damaged.
*1 Power terminal 2 is a common terminal that is also used for the
input signal. Do not use terminal 10 as a common terminal as
this will damage the internal circuitry.
*2 If a relay or other load is connected here, high voltage will be
applied to the input terminal and damage the internal circuitry.
•The transistor output of the H3CR-A@S is isolated from the internal
circuitry by a photocoupler, and can therefore be used either as an
NPN output type or a PNP (equivalent) output type.
Relationship between Input and Power
Supply Circuits (H3CR-AP)
Since the input circuit and the power supply circuit are configured
independently, the input circuit can be turned ON or OFF irrespective
of the ON/OFF state of the power supply.
It must be noted that a voltage equivalent to the power supply voltage
is applied to the input circuit.
If a relay or transistor is connected to two or more Timers, the input
terminals of those Timers must be wired properly so that they will not
be different in phase or the terminals will be short-circuited to one
another (refer to the figures below).
When using the timer in an environment where considerable noise
occurs, keep the input signal source device, timer unit, and wiring as
far away as possible from the source of the noise. It is also
recommended that shielded wire be used for the input signal wiring
as a countermeasure for noise.
Common to All H3CR-A Models
With the H3CR-AP, input wires must be as short as possible. If the
floating capacity of wires exceeds 1,200 pF (approx. 10 m for cables
with 120 pF/m), the operation will be affected. Pay particular
attention when using shielded cables.
The H3CR-A@S transistor output is isolated from the internal
circuitry by a photocoupler. Therefore, either NPN or PNP output is
possible.

Safety Precautions (H3CR-H)
Note: The undermentioned is common for all H3CR-H models.
■Power Supplies
The H3CR-H has a large inrush current; provide sufficient power
supply capacity. If the power supply capacity is too small, there may
be delays in turning ON the output.
With the H3CR-H
@
RL, for the power supply of an input device, use an
isolating transformer, of which the primary and secondary windings are
mutually isolated and the secondary winding is not grounded.
■Input/Output (H3CR-H@RL)
An appropriate input is applied to the input signal terminal of the Timer
when the input terminal for the input signal is short-circuited. Do not
attempt to connect any input terminal to any terminal other than the input
terminal or to apply voltage across other than the specified input
terminals or the internal circuits of the Timer may be damaged.
The H3CR-H@RL uses transformerless power supply. When
connecting a relay or transistor as an external signal input device,
pay attention to the following points to prevent short-circuiting due to
a sneak current to the transformerless power supply.
If input is made simultaneously from one input contact or a transistor
to the H3CR-H and a Timer whose common input terminals are used
as power terminals, such as the H3CR-A, a short-circuit current will
be generated. Either input through isolated contacts, or isolate the
power supply for one of the Timers.
■Wiring
The H3CR-H has a high impedance circuit. Therefore, the H3CR-H
may not be reset if the H3CR-H is influenced by inductive voltage. In
order to eliminate any influence of inductive voltage, the wires
connected to the H3CR-H must be as short as possible and should
not be installed alongside power lines. If the H3CR-H is influenced by
inductive voltage that is 30% or more of the rated voltage, connect a
CR filter with a capacitance of approximately 0.1 F and a resistance
of approximately 120 or a bleeder resistor between the power
supply terminals. If there is any residual voltage due to current
leakage, connect a bleeder resistor between the power supply
terminals.
■Operation
An interval of 3 s minimum is required to turn on the H3CR-H after
the H3CR-H is turned off. If the H3CR-H is turned on and off
repeatedly with an interval of shorter than 3 s, abnormal heating or
burning may occur in internal elements.
After the forced reset function of the H3CR-H is activated, an interval
of 3 s minimum is required to activate the forced reset function again.
If the forced reset function is activated repeatedly with an interval of
shorter than 3 s, the internal parts of the H3CR-H may deteriorate
and the H3CR-H may malfunction.
If it is required that the output be turned on repeatedly with an
interval of shorter than 3 s, consider use of the H3CR-A in mode D
(signal OFF-delay).
On the H3CR-F@, do not set both the ON set dial and OFF set dial to
the lowest settings. Doing so may damage the contacts.
■Others
If the H3CR-H is dropped or experiences some other kind of shock,
because a latching relay is used for output, contacts may be reversed
or go into a neutral state. If the H3CR-H is dropped, reconfirm correct
operation.

Safety Precautions for All H3CR Models
Note: The undermentioned is common for all H3CR models.
Warning Indications
Meaning of Product Safety Symbols
Risk of fire and explosion due to arcing and relay heat
generation that accompanies switching. Do not use in an
environment where flammable or explosive gas is present.
The H3CR series uses a transformer-less power
supply. Exercise full caution as there is a risk of
electrical shock if input terminal is touched when
power voltage is applied.
The service life of the output relay varies widely
depending on switching capacity and switching
conditions. Use only within the rated load and
electrical life count, based on actual conditions of use.
Risk of contact sticking and burning if used past the
service life. Always use a load current that does not
exceed the rating, and if a heater is used, use a thermal switch in the
load circuit.
Do not remove the outer casing.
In rare circumstances there is a risk of slight electrical
shock, fire, or device damage. Do not disassemble,
modify, repair, or otherwise touch the inside.
In rare circumstances there is a risk of fire if the
screws become loose. Tighten the terminal screws to
the specified torque (1.08N·m).
Do not use the Timer in the following locations.
•Locations with radical temperature changes.
•Locations with high humidity that may result in condensation.
•Locations with excessive vibration or shock.
•Locations with corrosive gas or dust.
•Locations where the Timer is exposed to sprayed water, oil, or
chemicals.
Pay the utmost attention not to make mistakes in polarity when wiring
the Timer.
Do not connect anything to terminals that are not used.
Risk of internal element damage if a voltage that exceeds the rating
is applied.
Using a surge absorber is recommended if surge voltages occur.
The H3CR Series uses a transformerless power supply. Do not touch
the input terminals while the supply voltage is applied, otherwise an
electric shock may be received.
Verify that the power and output LEDs (LCD) are operating normally.
In some usage environments, the LEDs/LCD/ resin components may
deteriorate faster than normal, resulting in display failure. Inspect and
replace regularly.
When disposing of this product, follow the procedures for disposal of
industrial waste that apply in your region.
Verify that the product is the desired product before use.
Exercise caution as the outer casing of the timer may be immersed in
organic solvents (thinner, benzene, etc.), strong alkali, or strong
acids.
Changing the Setting
Do not change the time unit, time range, or operation mode while the
Timer is in operation, otherwise the Timer may malfunction.
The time unit and time range can be set with the respective selectors
turned clockwise or counterclockwise.
The selectors are of notched so that they will snap when they are
properly set. Do not set the selectors midway between notches,
otherwise the Timer may break or malfunction.
Do not use H3CR-A models (except for H3CR-A@S) in flicker mode
at the lowest selector setting, or H3CR-F models at the lowest
selector setting. Doing so may result in damage to contacts.
CAUTION Indicates a potentially hazardous situation
which, if not avoided, may result in minor
or moderate injury or in property damage.

Power Supplies
A DC power supply can be connected if its ripple factor is 20% or
less and the mean voltage is within the rated operating voltage range
of the Timer.
An AC power supply can be connected to the power input terminals
without regard to polarity. A DC power supply must be connected to
the power input terminals as designated according to the polarity of
the terminals.
Make sure that the voltage is applied within the specified range,
otherwise the internal elements of the Timer may be damaged.
Connect the power supply voltage through a relay or switch in such a
way that the voltage reaches a fixed value at once, otherwise the
Timer may not be reset or a timer error may result.
Be aware that the operating voltage will rise by 5% if the rated
voltage is applied to the Timer continuously while the ambient
temperature is close to the maximum permissible ambient
temperature.
The power supply circuit of any H3CR-A model (except for H3CR-
A@S), H3CR-F 100-to-240-VAC model, and H3CR-G model is a
switching circuit. If the power line connected to the power supply
circuit has a transformer with high inductance, a counter-
electromotive voltage will be induced by the inductance. To suppress
the voltage, apply a CR filter to the power supply line.
Apply the power voltage at once through the switch and relay
contacts. If not applied at once, power reset may not take place or
time-up may occur.
When the power is turned on, a rush current (refer to your OMRON
website) may flow briefly and the timer may not start if there is
insufficient power capacity. Use a power supply with sufficient
capacity.
Mounting Direction
There are no restrictions to the mounting direction.
Precautions for EN61812-1
Conformance
The H3CR Series as a built-in timer conforms to EN61812-1
provided that the following conditions are satisfied.
Make sure that no voltage is applied to any terminals before
dismounting the Timer from the Socket.
The output section of the H3CR is provided only with basic isolation.
The H3CR itself is designed under the following conditions:
•Overvoltage category III
•Pollution degree 2
•Isolation
Operation parts: Reinforced isolation
−With clearance of 5.5 mm and creepage distance of 5.5 mm at
230 VAC
Output: Basic isolation (See note)
−With clearance of 3 mm and creepage distance of 3 mm at
230 VAC
Note: The 11-pin model ensures basic isolation by itself and also
ensures basic isolation with the 11-pin model mounted to the
OMRON P2CF-11-@ or P3GA-11 Socket.
Connect the two output contacts different in polarity to the loads so
that they will be the same in potential.
Others
If the Timer is mounted to a control board, dismount the Timer from
the control board or short-circuit the control board circuitry before
carrying out a voltage withstand test between the electric circuitry
and non-charged metal part of the Timer. This protects the internal
circuitry of the Timer from damage.
If the timer is left for an extended time at high temperature in the
time-up state (internal relay ON), the internal components
(electrolytic capacitors, etc.) may deteriorate faster than normal. For
this reason, use in combination with a relay, and avoid leaving in the
time-up state for an extended time (for example, one month or
longer). (Excluding H3CR-H)
Reference example
Use as shown below.
