1. APPLICATION

1.1. Product application

The time delay relay REV-120 is the microprocessor-based device intended for on/off switching the load in
user-defined time intervals.

REV-120 can be operated by ten operation modes:

 on-delay;
 time delay when energizing;
 periodic with on-delay;
 periodic with time delay when energizing;
 off-delay (when control contact opening);
 pulse I (when control contact closing);
 pulse II (when control contact opening);
 on/off delay (according to control contact);
 pitch of the load relay (during each control contact closing);
 pulse generator of 0.5 s.
