Time Relays - Switch-on and Switch-off Delay

Nano ICCS Time Relay – switch-on and switch-off delay – are used to switch on or off a load after a given time.

The supply voltage is applied to terminal 30. As soon as signal voltage is applied to terminal 15 the relay switches on after the given delay time is expired. When the signal voltage is removed from terminal 15 the relay switches off after the defined delay time.
