Screw Terminals).
*1
• Character height of 12 mm for better readability (on models with 4 digits).
• The present value display characters can be switched between red, green,
and orange.
*2
Safety and Reliability
• Power supply circuit and input circuits are isolated for safety and reliability.
*3
• New set value limit and output counter functions have been added.
*4
Other Features
• Front Panel can be changed to white or light gray.
*5
• Models with instantaneous contact output added to the series.
*1.
For 100 to 240 VAC Models with Screw Terminals 78 mm, Models with Sockets: 63.7 mm
(case dimension).
*2.
The H5CX-A11, H5CX-L8 and H5CX-B Timers have only red characters.
*3.
Specifications: 100 to 240 VAC
*4.
The value of the output counter can only be monitored. It cannot be reset.

Features
Basic Features
Ultra Short Body
The body depth has been greatly reduced. Helps in making thinner
control panels. (Models with Screw Terminals)
24-VAC / 12 to 24-VDC Models with Screw Terminals: 59 mm
100 to 240-VAC / VDC Models with Screw Terminals: 78 mm
*
Models with Sockets: 63.7 mm (case dimension)
*
The shortest body for a timer with isolated power supply and input circuits and a maximum
ambient temperature of 55°C (according to OMRON investigation in June 2009).
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.

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.

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.

Worry-free operation
is achieved with the
New H5CX by
restricting the time
that can be set.
(Display example)
Note:
The H5CX-A11 and H5CX-L8 Timers have only red characters.
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 Timrrer or the load.
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.

Other Features
Change the Front Panel Color
The Front Panel can be replaced with an optional Front Panel (order
separately) with a different color to match the installation site. Select
from black, white, and light gray.
Universal NPN/PNP Input
DC 2-wire sensors can be connected for a wide range of input
devices.
Waterproof, Dust-proof Structure (UL508 Type
4X and IP66)
Worry-free
application is possible in locations subject to water.

New Modes
Modes, such as a stopwatch mode (Mode S), have been added.
Select any of 15 modes.
Models with Instantaneous Contact Output
Models with instantaneous contact outputs have been added to the
lineup for use with self-holding circuits and as auxiliary relays. These
models are also convenient when replacing analog timers.
