Safety and Reliability
Isolated Power Supply and Input Circuits
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 H5CZ removes these worries.

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 H5CZ
by restricting the time
that can be set.
Output Counter
The output counter counts the number of times the output turns ON
(alarm display, count monitoring, count in increments of 1,000). This
counter is useful in managing the service life of the Timer or the load.
Other Features
Models with Instantaneous Contact Output
Models with instantaneous contact outputs have been added for use
with self-holding circuits and as auxiliary relays. These models are
also convenient when replacing analog timers.
Waterproof, Dust-proof Structure (UL508 Type
4X and IP66)
Worry-free application is possible in locations subject to water.
Note: When the Y92S-29 Waterproof Packing is used.
Key Protection
Select from any of seven protection patterns. Use the best one for the
application.
New Modes
Modes, such as a stopwatch mode (Mode S), have been added.
Select any of 15 modes.
