Character Height of 10 mm with a Wide Viewing Angle.
Operation is simplified by the Up/Down Keys for each digit on 4-digit.
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.
You can set an upper limit for the set value to prevent unexpected operation of output devices caused by setting mistakes.
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.
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.
Worry-free application is possible in locations subject to water.

Select from any of seven protection patterns. Use the best one for the application.
Modes, such as a stopwatch mode (Mode S), have been added.
