Without Reset Input (H3CR-H8L)
Reference:
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.
The minimum applicable load is 10 mA at 5 VDC for H3CR-H8L/-HRL
and 100 mA at 5 VDC for H3CR-H8RL (failure level: P).

Reset
Control output
Turns off the control output and resets the elapsed time.
Operates instantaneously when the power is turned on and time-limit resets when the set time is up
after the power is turned off.
