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

250 VAC/30 VDC
(cosφ = 1)
Reference: A maximum current of 0.15 A can be switched at 125 VDC (cosφ = 1) and
a maximum current of 0.1A can be switched at 125V DC and L/R = 7ms.
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).
