Features
Basic Features
Ultra Short Body
The body depth has been greatly reduced. Helps in making thinner
control panels. (Models with Screw Terminals)
Easier to Read
For better readability, the character height for the present value display
is 12 mm (on models with 4 digits), the largest class in the industry. The
wide viewing angle and brightness provide excellent visibility.
The number of display segments has also been increased to make settings
easier to understand, and the present value display can be switched between
red, green and orange so that output status can be seen from a distance.
Note: The H5CX-A11 and H5CX-L8 Timers have only red characters.
The Easiest Operation
Operation is simplified by the
Up/Down Keys for each digit
on 4-digit models and Up Keys
for each digit on 6-digit
models.
Safety and Reliability
Isolated Power Supply and Input Circuits *1
Power supply circuit and input circuits are isolated for safety and
reliability.
Previous non-isolated timers had wiring restrictions and could be damaged if
wired incorrectly. The New H5CX removes these worries.
*1. New Models (H5CX-@-N) with 100 to 240-VAC specifications.
Set Value Limit
You can set an upper limit for the set value to prevent unexpected
operation of output devices caused by setting mistakes.
Output Counter
An output counter counts the number of times that the output turns
ON. (An alarm can be set and the value of the output counter can be
monitored, Unit: 1,000 operations.) This counter is useful in managing
the service life of the Timer or the load.
Refer to “Safety Precautions” on page 41.

safety standards, refer to your OMRON website.

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.

Accessories (Order Separately)
Front Panel (Replacement Part)
You can change the color of the front panel when mounting the Timer.
The Timer is shipped with a black (N1.5) Front Panel. Protecting the Timer in Environments Subject to Oil
The Waterproof Packing will deteriorate, harden, and shrink
depending on the application environment. To ensure maintaining the
IP@6, UL Type 4X waterproof level, periodically replace the
Waterproof Packing. The periodic replacement period will depend on
the application environment. You must confirm the proper
replacement period. Use 1 year or less as a guideline. If the
Waterproof Packing is not replaced periodically, the waterproof level
will not be maintained.
It is not necessary to mount the Waterproof Packing if waterproof
construction is not required.
Note:
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.

Replacement Method
The Front Panel is attached to
the Terminal with tabs in four
locations. To remove the Front
Panel, open the tabs and pull the
Front Panel forward.
To attach the Front Panel, press
it onto the Timer so that all four
tabs lodge into the groves on the
body of the Timer.

Grooves
The H5CX's panel surface is water-resistive (IP@6, UL Type 4X)
and so even if drops of water penetrate the gaps between 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.

Explanation of Functions
Operating Procedures for Timer Function
Items marked with stars () can be set using the DIP switch.
Time Range (timr)
Set the range to be timed in the range 0.001 s to 9,999 h.
Settings of type ---- h (9,999 h) and ---- min (9,999 min) cannot be
made with the DIP switch. Use the operation keys if these settings are
required.
Timer Mode (timm)
Set either the elapsed time (UP) or remaining time (DOWN) mode.
In UP mode, the elapsed time is displayed, and in DOWN mode, the
remaining time is displayed.
Output Mode (outm)
Set the output mode.
The possible settings are A, A-1, A-2, A-3, b, b-1, d, E, F, Z and S.
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 20.)
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, A-3, b, b-1 or S.
If the output time is set to 0.00, hold is displayed, and the output is
held.
Input Signal Width (iflt)
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 (signal, reset, and gate
inputs).
If contacts are used for the input signal, set the input signal width to
20 ms.
Processing to eliminate chattering 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.
Set an NPN input when using a 2-wire sensor.
For details on input connections, refer to "Input Connections" on
page 9.
Display Color (colr)
(Terminal block model: H5CX-A@ only)
Set the color used for the present value.
Key Protect Level (kypt)
Set the key protect level.
Refer to “Key Protect Level” on page 32.
Instantaneous/Time-limit (otmd)
Set the contact output to time-limit SPDT + instantaneous SPDT or
time-limit SPDT operation.
Set Value Upper Limit (sl-h)
Set the upper limit for the set value when it is set in Run Mode.
The limit can be set to between 1 and 9999.
This setting does not apply to the ON duty in Z mode.
Output ON Count Alarm Set Value (on-a)
Set the alarm value for the output ON count.
The limit can be set to between 0 x 1000 (0 times) and 9999 x 1000
(9,999,000 times). Only the underlined values are set. The alarm will
be disabled if 0 is set.
If the total ON count of the output exceeds the alarm set value, e3 will
be displayed on the Timer to indicate that the output ON count alarm
value was exceeded. Refer to “Self-diagnostic Function” on page
32 for information on the e3 display.
ON Count Alarm Set Values for Outputs 1 and 2 (OUT1
and OUT2) (on1a and on2a)
Set the ON count alarm values for the outputs 1 and 2.
The limit can be set to between 0 x 1000 (0 times) and 9999 x 1000
(9,999,000 times). Only the underlined values are set. The alarm will
be disabled if 0 is set.
If the total ON count of instantaneous output 1 or 2 exceeds the alarm
set value, e3 will be displayed on the Timer to indicate that the output
ON count alarm value was exceeded. Refer to “Self-diagnostic
Function” on page 32 for information on the e3 display.
Output ON Count Monitor Value (on-c)
The monitor value is only displayed. It cannot be set.
The output ON count will be 1,000 times the displayed value.
ON Count Monitor Values for Outputs 1 and 2 (OUT1 and
OUT2) (on1c and on2c)
The monitor value for output 1 or 2 is only displayed. It cannot be set.
The output ON count will be 1,000 times the displayed value.

Operating Procedures for Timer Function
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 function 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. Set the ON duty ratio used in ON/
OFF-duty-adjustable flicker mode (Z) as a percentage.
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. When Time Range = - - - - s (9999 s)
Rounded off to the nearest integer (because of the
time range setting) → ON time = 6 s
2. When Time Range = - -. - - s (99.99 s)
Rounded off to 2 decimal places (because of the time
range setting) → ON time = 6.20 s
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.
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. Set the cycle time.

• 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.

Mode A: Signal ON delay (Timer resets when power comes ON.)
Basic operation Detailed operation
*Start signal input is disabled during timing.
• Timing starts when the start signal goes ON.
• While the start signal is ON, the timer starts when the
power comes ON or when the reset input goes OFF.
• A sustained control output is used.
• Timing stops when the time is up.
Note: Output is instantaneous when the set value is 0. The names in parentheses are used for the absolute value setting.
Mode F-1: Cumulative (Timer does not reset when power comes ON.)
Basic operation Detailed operation
• Start signal enables timing (timing is stopped when the
start signal is OFF or when the power is OFF).
• A sustained control output is used.
• Timing continues even after the time is up.
Note: Output is instantaneous when the set value is
0.
When the H5CX is used with power start, 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.

Safety Precautions for All H5CX Series (Common)
Do not allow pieces of metal, wire clippings, or fine
metallic shavings or fillings from installation to enter
the product. Doing so may occasionally result in
electric shock, fire, or malfunction.
Minor injury due to explosion may occasionally occur.
Do not use the Timer where subject to flammable or
explosive gas.
Fire may occasionally occur. Tighten the terminal
screws to the rated torque.
H5CX terminals: 6.55 to 7.97 lb-in (0.74 to 0.90 N m)
P2CF Socket terminals: 4.4 lb-in (0.5 N m)
Minor injury due to electric shock may occasionally
occur. Do not touch any of the terminals while power
is being supplied. Be sure to mount the terminal cover
after wiring.
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. If the output relay is used beyond its life
expectancy, its contacts may become fused or there may be a
risk of fire. Also, be sure that the load current does not exceed
the rated load current and when using a heater, be sure to use a
thermal switch in the load circuit.
Minor electric shock, fire, or malfunction may
occasionally occur. Do not disassemble, modify, or
repair the Timer or touch internal components.
• The panel surface of the H5CX is water-resistant (conforming to
NEMA4, IP66, UL Type 4X (Indoor Use Only). To protect the
internal circuits from water penetration through the space between
the H5CX and operating panel, waterproof packing is included.
Attach the Y92F-30 Adapter with sufficient pressure with the
reinforcing screws so that water does not penetrate the panel.
• When mounting the Timer to a panel, tighten the two mounting
screws alternately, a little at a time, so as to keep them at an equal
tightness. If the panel screws are tightened unequally, water may
enter the panel.
• Store the Timer at the specified temperature. If the Time has been
stored at a temperature of less than -10°C, allow the Time to stand
at room temperature for at least 3 hours before use.
• Mounting the Timer side-by-side may reduce the life expectancies
of internal components.
• Use the Timer within the specified ranges for the ambient operating
temperature and humidity.
• Do not use in the following locations:
• Locations subject to sudden or extreme changes in temperature.
• Locations where high humidity may result in condensation.
• Do not use the Timer outside of the rated ranges for vibration,
shock, water exposure, and oil exposure.
• Do not use this Timer in dusty environments, in locations where
corrosive gasses are present, or in locations subject to direct
sunlight.
• Install the Timer well away from any sources of static electricity,
such as pipes transporting molding materials, powders, or liquids.
• Internal elements may be destroyed if a voltage outside the rated
voltage range is applied.
• Be sure that polarity is correct when wiring the terminals.
• Separate the Timer from sources of noise, such as devices with
input signals from power lines carrying noise, and wiring for I/O
signals.
• Do not connect more than two crimp terminals to the same
terminal.
• Up to two wires of the same size and type can be inserted into a
single terminals.
• Use the specified wires for wiring.
Applicable Wires: AWG 18 to AWG 22, solid or twisted, copper.
Wiring stripping length: 5 to 6 mm (recommended)
• Install a switch or circuit breaker that allows the operator to
immediately turn OFF the power, and label it to clearly indicate its
function.
• When the Timer is operated with no-voltage input (NPN input),
approximately 14 V is output from the input terminals. Use a sensor
that contains a diode.
• Use a switch, relay, or other contact so that the rated power supply
voltage will be reached within 0.1 seconds. If the power supply
voltage is not reached quickly enough, the Timer may malfunction
or outputs may be unstable.
• Use a switch, relay, or other contact to turn the power supply OFF
instantaneously. Outputs may malfunction and memory errors may
occur if the power supply voltage is decreased gradually.
•H5CX-A@-N/-L@-N:
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.)
When in the remaining time mode, the amount the set value is
changed is added to or subtracted from the present value.
Operation with a set value of 0 will vary with the output mode. Refer
to the timing charts on page 20.
•H5CX-B@-N:
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:
1. Forecast Value Setting
When the present value ≥ the set value, OUT2 (control output)
turns ON.
When the present value ≥ the forecast value (forecast value =
set value - forecast set value), OUT1 (forecast output) turns ON.
2. Absolute Value Setting
When the present value ≥ set value 2, OUT2 (control output 2)
turns ON.
When the present value ≥ the forecast value (forecast value =
set value - forecast set value), OUT1 (control output 1) turns
ON.
When the set value is 0, the output turns ON the moment the
signal is input. The reset operation turns OFF the output.
• Do not use organic solvents (such as paint thinners or benzine),
strong alkali, or strong acids. They will damage the external finish.
• Confirm that indications are working normally, including the
backlight LED, and LCD. The indicator LEDs, LCD, and resin parts
may deteriorate more quickly depending on the application
environment, preventing normal indications. Periodic inspection
and replacement are required.
• The waterproof packing may deteriorate, shrink, or harden
depending on the application environment. Periodic inspection and
replacement are required.

• H5CX models with a 24-VDC/12 to 24-VDC power supply use a
transformer-free power supply method in which the power supply
terminals are not isolated from the signal input terminals. If a non-
isolating DC power supply is used, unwanted current paths may
occasionally burn or destroy internal components depending on
the wiring. Always check the wiring sufficiently before use.
• An inrush current of approx. 10 A will flow for a short time when the
power supply is turned ON. If the capacity of the power supply is
not sufficient, the Timer may not start. Be sure to use a power
supply with sufficient capacity.
• Maintain voltage fluctuations in the power supply within the
specified operating voltage range.
• When turning the power ON and OFF, input signal reception is
possible, unstable, or impossible as shown in the diagram below.
• To allow for the startup time of peripheral devices (sensors, etc.),
the Timer starts timing operation between 200 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 249
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. The present value
display will start from 250 ms. (Normal operation is possible for set
values of 250 ms or more.) In applications where a set value of 249
ms or less is required, use start timing with signal input.
• Inrush current generated by turning ON or OFF the power supply
may deteriorate contacts on the power supply circuit. Turn ON or
OFF to a device with the rated current of more than 10 A.
• Make sure that all settings are appropriate for the application.
Unexpected operation resulting in property damage or accidents
may occur if the settings are not appropriate.
• Do not leave the Timer for long periods at a high temperature with
output current in the ON state. Doing so may result in the
premature deterioration of internal components (e.g., electrolytic
capacitors).
• EEPROM is used as backup memory when the power is
interrupted. The write life of the EEPROM is 100,000 writes.
The EEPROM is written at the following times:
• When the power supply is turned OFF
• When switching from Timer/Twin Timer Selection Mode or
Function Setting Mode to Run Mode
• Dispose of the product according to local ordinances as they apply.
• Attach the front panel when using the Timer. The tabs in the middle
of each of four sides secure the front panel to the main body. To
remove the panel, widen the four tabs and pull the panel toward
you. To mount the panel, fit all four tabs correctly into the grooves
on the main body.
• When conforming to EMC standards, refer to the information
provided in this datasheet for cable selection and other conditions.
• This is a class A product. In residential areas it may cause radio
interference, in which case the user may be required to take
adequate measures to reduce interference.
•H5CX-A@-N/-L@-N:
Basic insulation is provided between the power supply and input
terminals. (No insulation is provided between the power supply and
input terminals for the H5CX-@D-N.)
Basic insulation is provided between power supply and output
terminals, and between input and output terminals.
•H5CX-B@-N:
No insulation is provided between the power supply and input
terminals.
Basic insulation is provided between the power supply and output
terminals.
• When double insulation or reinforced insulation is required, apply
double insulation or reinforced insulation as defined in IEC 60664
that is suitable for the maximum operating voltage with clearances
or solid insulation.
• Connect the input and output terminals to devices that do not have
any exposed charged parts.
