The Model 392 Interval Lockout Timer is useful when you wish to de-energize the relay for a set period of time. Power is applied to the coil all the time. The Dry contact must close the initiate switch and re-open to energize the relay for the On time setting. At the end of the On time, the relay will de-energize and remain de-energized for the lockout time period. Closing and re-opening the initiate switch during the timing has no effect on the operation of the relay. At the end of the Lockout time the relay can be operated as before. An SG version of this model is available using silver with gold flash contacts.
