Digital Timer H5CZ

Better Readability

Character Height of 10 mm with a Wide Viewing Angle.

The Easiest Operation

Operation is simplified by the Up/Down Keys for each digit on 4-digit.

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.

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.

I/O Functions

For details, refer to the timing charts on Data Sheet.

Inputs *	Start signal	Normally functions to start timing. In modes A-2 and A-3, disable timing. In mode S, starts and stops timing.
Inputs *	Reset	• Resets present value. (In elapsed time mode, the present value returns to 0; in remaining time mode, the present value returns to the set value.) • Count inputs are not accepted and control output turns OFF while reset input is ON. • Reset indicator is lit while reset input is ON.
Outputs	Control output (OUT)	Outputs take place according to designated operating mode when timer reaches corresponding set value.
