Life-test Curve (Reference Values)

H5CX_Spec4

A maximum current of 0.15 A can be switched at 125 VDC (cosφ =1) and a maximum current of 0.1
A can be switched if L/R is 7 ms. In both cases, a life of 100,000 operations can be expected.

I/O Functions

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

Inputs
*1
Start signalNormally functions to start timing.
In modes A-2 and A-3, disable timing. In mode S, starts and stops timing.
ResetResets 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.
Gate *2Disables timing. (If a reset occurs while the gate input is ON, a reset will be performed.)
OutputsControl output
(OUT)
Outputs take place according to designated operating mode when timer reaches corresponding set value.

*1.The H5CX-L8E[] does not have an input.

*2.The H5CX-L[] does not have a gate input.
