■Characteristics
Note 1. The values are based on the set value.
2. The value is applied for a minimum pulse width of 1 ms.
3. To meet UL listing requirements with H5CX-L8@/-A11@ models, an OMRON P2CF-08-@ or P3G-08 Socket must be mounted on the Timer.
Otherwise, H5CX-L8@/-A11@ models are considered to meet UL508 recognition requirements.
4. The Y92S-29 Waterproof Packing and Y92F-30 Flush Mounting Adapter are necessary to ensure IP66, NEMA4, and UL Type 4X water-
proofing between the H5CX and installation panel.

Note: 1. Depending on the operating environment, the condition of
resin products may deteriorate, and may shrink or become
harder. Therefore, it is recommended that resin products
are replaced regularly.
2. The H5CX’s panel surface is water-resistive (conforming to
IP66) and so even if drops of water penetrate the gaps be-
tween the keys, there will be no adverse effect on internal
circuits. If, however, there is a possibility of oil being present
on the operator’s hands, use the Soft Cover. The Soft Cover
ensures protection equivalent to IP54 against oil. Do not,
however, use the H5CX in locations where it would come in
direct contact with oil.
Note: Order the Flush Mounting Adapter separately if it is lost or dam-
aged.
Note: Use Waterproof Packing to provide a level of water protection
that complies with NEMA4, UL Type 4X, or IP66 standards. Or-
der the Waterproof Packing separately if it is lost or damaged.
Depending on the operating environment, the Waterproof
Packing may deteriorate, contract, or harden and so regular re-
placement is recommended.

Explanation of Functions
Time Range (timr) (Setting possible using DIP switch.)
Set the range to be timed in the range 0.000 s to 9,999 h. Settings of
type ---- h (9,999 h) and ---- min (9,999 min) cannot, however, be
made with the DIP switch. Use the operation keys if these settings
are required.
Timer Mode (timm) (Setting possible using DIP switch.)
Set either the elapsed time (UP) or remaining time (DOWN) mode.
Output Mode (outm) (Setting possible using DIP switch.)
Set the output mode. The possible settings are A, A-1, A-2, A-3, b, b-
1, d, E, F, and Z. Only output modes A, A-2, E, and F can be set
using the DIP switch. Use the operation keys if a different setting is
required. (For details on output mode operation, refer to Timing
Charts on page 22.)
Output Time (otim)
When using one-shot output, set the output time for one-shot output
(0.01 to 99.99 s). One-shot output can be used only if the selected
output mode is A, A-1, A-2, b, or b-1. If the output time is set to 0.00,
hold is displayed, and the output is held.
Input Signal Width (iflt) (Setting possible using DIP
switch.)
Set the minimum signal input width (20 ms or 1 ms) for signal, reset,
and gate inputs. The same setting is used for all external inputs (sig-
nal, reset, and gate inputs). If contacts are used for the input signal,
set the input signal width to 20 ms. Processing to eliminate chatter-
ing is performed for this setting.
NPN/PNP Input Mode (imod)
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. The same setting is used for all external
inputs. For details on input connections, refer to Input Connections
on page 9.
Display Color (colr)
Set the color used for the present value.
Key Protect Level (kypt)
Set the key protect level.
When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by specifying the
key protect level (KP-1 to KP-5). The key protect indicator is lit while the key-protect switch is set to ON.
Note: Changing mode to timer/twin timer selection mode ( + 1 s min.) or function setting mode ( 3 s min.).

Operation in Run Mode
Present Value and Set Value
These items are displayed when the power is turned ON. The
present value is displayed in the main display and the set value is
displayed in the sub-display. The values displayed will be determined
by the settings made for the time range and the timer mode in func-
tion setting mode.
Present Value and ON Duty Ratio (Output Mode = Z)
The present value is displayed in the main display and the ON duty
ratio is displayed in the sub-display. “SET1” lights at the same time.
Set the ON duty ratio used in ON/OFF-duty adjustable flicker mode
(Z) as a percentage.
If a cycle time is set, cyclic control can be performed in ON/OFF-duty
adjustable flicker mode simply by changing the ON duty ratio.
The output accuracy will vary with the time range, even if the ON duty
ratio setting is the same. Therefore, if fine output time adjustment is
required, it is recommended that the time range for the cycle time is
set as small as possible.
Examples:
1. If the cycle time is 20 s, the ON duty ratio is 31%, and the time
range is 1 s to 9999 s, the ON time is given by the following:
20 (s) × = 6.2 (s) → Rounded off to the nearest integer
(because of the time range setting) → ON time = 6 s
2. If the cycle time is 20.00 s, the ON duty ratio is 31%, and the time
range is 0.01 s to 99.99 s, the ON time is given by the following:
20.00 (s) × = 6.200 (s) → Rounded off to 2 decimal places
(because of the time range setting) → ON time = 6.20 s
Present Value and Cycle Time (Output Mode = Z)
The present value is displayed in the main display and the cycle time
is displayed in the sub-display. “SET2” lights at the same time.
Set the cycle time used in ON/OFF-duty adjustable flicker mode (Z).

Explanation of Functions
OFF Time Range (oftr) (Setting possible using DIP
switch.)
Set the time range for the OFF time in the range 0.000 s to 9,999 h.
Only settings of type --.-- s (99.99 s), ---.- s (999.9 s), ---- s (9,999 s),
and -- min -- s (99 min 59 s), however, can be made with the DIP
switch. Use the operation keys if another type of setting is required.
ON Time Range (ontr) (Setting possible using DIP
switch.)
Set the time range for the ON time in the range 0.001 s to 9,999 h.
Only settings of type --.-- s (99.99 s), ---.- s (999.9 s), ---- s (9,999 s),
and -- min -- s (99 min 59 s), however, can be made with the DIP
switch. Use the operation keys if another type of setting is required.
Timer Mode (timm) (Setting possible using DIP switch.)
Set either UP (incremental) or DOWN (decremental) timer mode. In
UP mode, the elapsed time is displayed, and in DOWN mode, the
remaining time is displayed.
ON/OFF Start Mode (totm) (Setting possible using DIP
switch.)
Set the output mode. Set either flicker OFF start or flicker ON start.
(For details on output mode operation, refer to Timing Charts on
page 30.)
Input Signal Width (iflt) (Setting possible using DIP
switch.)
Set the minimum signal input width (20 ms or 1 ms) for signal, reset,
and gate inputs. The same setting is used for all external inputs (sig-
nal, reset, and gate inputs). If contacts are used for the input signal,
set the input signal width to 20 ms. Processing to eliminate chatter-
ing is performed for this setting.
NPN/PNP Input Mode (imod)
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. The same setting is used for all external
inputs. For details on input connections, refer to Input Connections
on page 9.
Display Color (colr)
Set the color used for the present value.
Key Protect Level (kypt)
Set the key protect level.
When the key-protect switch is set to ON, it is possible to prevent setting errors by prohibiting the use of certain operation keys by specifying the
key protect level (KP-1 to KP-5). The key protect indicator is lit while the key-protect switch is set to ON.
Note:Changing mode to timer/twin timer selection mode ( + 1 s min.) or function setting mode ( 3 s min.).

■Operation in Timer/Twin Timer Selection Mode
Select whether the H5CX is used as a timer or a twin timer in timer/twin timer selection mode. The H5CX is also equipped with a DIP switch monitor
function, a convenient function that enables the settings of the DIP switch pins to be confirmed using the front display.
Note 1. When the mode is changed to timer/twin timer selection mode, the present value is reset and output turns OFF. Timing operation is not
performed in timer/twin timer selection mode.
2. Setting changes made in timer/twin timer selection mode are enabled when the mode is changed to run mode. If settings are changed, the
HC5X is automatically reset (present value initialized, output turned OFF).

■Accessories (Order Separately) Note: 1. Depending on the operating environment, the condition of
resin products may deteriorate, and may shrink or become
harder. Therefore, it is recommended that resin products
are replaced regularly.
2. The H5CX’s panel surface is water-resistive (conforming to
IP66) and so even if drops of water penetrate the gaps be-
tween the keys, there will be no adverse effect on internal
circuits. If, however, there is a possibility of oil being present
on the operator’s hands, use the Soft Cover. The Soft Cover
ensures protection equivalent to IP54F against oil. Do not,
however, use the H5CX in locations where it would come in
direct contact with oil.
Note: Order the Flush Mounting Adapter separately if it is lost or dam-
aged.
Note: Use Waterproof Packing to provide a level of water protection
that complies with NEMA4, UL Type 4X, or IP66 standards. Or-
der the Waterproof Packing separately if it is lost or damaged.
Depending on the operating environment, the Waterproof
Packing may deteriorate, contract, or harden and so regular re-
placement is recommended.

Safety Precautions (Common)
Refer to Safety Precautions for All Timers.
Note: The following precautions are common for all H5CX models.
Loose screws may occasionally result in fire or malfunction. Tighten
the terminal screws securely. The recommended tightening torque
is 0.5 N·m.
There may occasionally be a risk of explosion. Do not use the
product where flammable or combustion gases are present.
This may occasionally cause electric shock, fire or malfunction.
Never disassemble, repair or modify the product.
This may occasionally cause electric shock, fire or malfunction.
Do not allow metal fragments or lead wire scraps to fall inside this
product.
If both the power supply for the input device and that for the timer
are not insulated, unwanted current from the AC power supply
may occasionally burn out or damage the internal parts. Always
use an insulated power supply for the timer.
■Precautions for Safe Use
The following precautions must be observed to ensure safety.
Operating and Storage Conditions
•Do not use in locations affected by excessive vibration or shock, or
in locations subject to exposure to water or oil.
•Do not use the product in locations subject to dust, corrosive
gases, or direct sunlight.
•Separate the input signal devices, input signal cables, and the
product from the source of noise or high-tension cables producing
noise.
•Separate the product from the source of static electricity when
using the product in an environment where a large amount of static
electricity is produced (e.g., forming compounds, powders, or fluid
materials being transported by pipe).
•Organic solvents (such as paint thinner), as well as very acidic or
basic solutions might damage the outer casing of the H5CX.
•Use the product within the ratings specified for temperature and
humidity.
•Do not use the product in locations where condensation may occur
due to high humidity or where temperature changes are severe.
•Store at the specified temperature. If the H5CX has been stored at
a temperature of less than –10°C, allow the H5CX to stand at room
temperature for at least 3 hours before use.
Usage Precautions
•Make sure that the voltage applied is within the specified range,
otherwise the internal elements of the counter may be damaged.
•The load current must be within the rated current.
•Ensure that the power is turned OFF before changing DIP switch
settings. Changing DIP switch settings with the power turned ON
may result in electric shock due to contact with terminals subject to
high voltages.
•Pay attention to terminal polarity to ensure correct wiring.
•Make sure that the fluctuation of the supply voltage is within the
permissible range.
•Apply the power supply voltage through a relay or switch in such a
way that the voltage reaches the rated value within 2 s. If the
voltage is applied gradually, the power may not be reset or unstable
output operations may result.
•Leaving the H5CX with outputs ON at a high temperature for a long
time may hasten the degradation of internal parts (such as
electrolytic capacitors). Therefore, use the product in combination
with relays and avoid leaving the product as long as more than 1
month with the output turned ON.
•When the product is operated with no-voltage input (NPN input),
approximately 14 V is output from the input terminals, so connect a
diode if the external power supply is less than 14 V.
•Install a switch or circuit-breaker that allows the operator to
immediately turn OFF the power, and make sure it is labeled
clearly.
•The H5CX’s panel surface is water-resistive (conforming to NEMA
4, UL Type 4X, and IP66). In order to prevent the internal circuit
from water penetration through the space between the H5CX and
operating panel, attach a waterproof packing (Y92S-29) between
the H5CX and installation panel and secure the waterproof packing
with the Y92F-30 Flush-mounting Adapter.
•Tighten the two mounting screws on the Adapter. Tighten them
alternately, a little at a time, so as to keep them at an equal
tightness. If the panel screws are tightened unequally, water may
ingress inside the panel.

■Precautions for Correct Use
Power Supplies
Turn the power ON and OFF using a relay with a rated capacity of 10
A minimum to prevent contact deterioration due to inrush current
caused by turning the power ON and OFF.
Be sure that the capacity of the power supply is large enough,
otherwise the Timer may not start due to inrush current that may flow
for an instant when the Timer is turned on.
When turning the power ON and OFF, input signal reception is
possible, unstable, or impossible as shown in the diagram below.
Timer Control with Power Start
To allow for the startup time of peripheral devices (sensors, etc.), the
H5CX starts timing operation between 200 ms to 250 ms after power
is turned ON. For this reason, in operations where timing starts from
power ON, the time display will actually start from 250 ms. If the set
value is 249 ms or less, the time until output turns ON will be a fixed
value between 200 and 250. (Normal operation is possible for set
value of 250 ms or more.) In applications where a set value of
249 ms or less is required, use start timing with signal input.
When the H5CX is used with power start in F mode or F-1 mode (i.e.,
accumulative operation with output on hold), there will be a timer
error (approximately 100 ms each time the H5CX is turned ON) due
to the characteristics of the internal circuitry. Use the H5CX with
signal start if timer accuracy is required.
Transistor Output
The transistor output of the H5CX is insulated from the internal
circuitry by a photocoupler, so the transistor output can be used as
both NPN and PNP output.
The diode connected to the collector of the output transistor is used
to absorb inverted voltage that is generated when an inductive load
is connected to the H5CX.
Response Delay Time When Resetting
(Transistor Output)
The following table shows the delay from when the reset signal is
input until the output is turned OFF.
(Reference value)
Power Failure Backup
All data is stored in the EEPROM when there is a power failure. The
EEPROM can be overwritten more than 100,000 times.
■Conformance to EN/IEC
Standards
There is no insulation between power supply and input terminals
(except for H5CX-A11/-A11S).
Basic insulation between power supply and output terminals, and
between input terminals and output terminals.
When double insulation or reinforced insulation is required, apply
double insulation or reinforced insulation defined in IEC 60664 that is
suitable for the maximum operating voltage with clearances or solid
insulation.

Safety Precautions (H5CX-A/-L)
If the output relay is used beyond its life expectancy, its contacts
may occasionally become fused or there may occasionally be a risk
of fire. The life expectancy of the output relay varies considerably
according to its usage. Use the output relay within its rated load and
electrical life expectancy.
Depending on the wiring, unwanted current from the AC power
supply may occasionally burn out (damage) the internal parts.
The H5CX-A/-L (except for H5CX-A11/-A11S) do not have
transformers. Therefore, there is no insulation between the power
supply and input terminals, so make sure that wiring is correct before
use.
For the power supply of an input device of the H5CX (except for
H5CX-A11/-A11S), use an isolating transformer with the primary and
secondary windings mutually isolated and the secondary winding not
grounded.
Correct Wiring Example
Incorrect Wiring Example 1
Do not ground the secondary winding. If the secondary wiring is
grounded, as shown in the following diagram, unwanted current may
occasionally burn out or damage the internal parts.
Incorrect Wiring Example 2
Do not simultaneously input signals from a single input contact or a
transistor to two or more timers that have independent power
supplies. Otherwise, the internal parts may occasionally be burnt out
or damaged by unwanted current, as shown in the following diagram.
■Precautions for Safe Use
Usage Precautions
Do not touch the input terminals while power is supplied. The H5CX
(except for H5CX-A11/-A11S) has a transformerless power supply
and so touching the input terminals with power supplied may result in
electric shock.
Changing the Set Values
When changing the set value during a timing operation, the output
will turn ON if the set value is changed as follows because of the use
of a constant read-in system:
Elapsed time (UP) mode: Present value ≥ set value
Remaining time (DOWN) mode: Elapsed time ≥ set value
(The present value is set to 0.)
Note:When in the remaining time mode, the amount the set value is
changed is added to or subtracted from the present value.
■Precautions for Correct Use
Operation with a Set Value of 0
Operation with a set value of 0 will vary with the output mode. Refer
to the Timing Charts.
