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.
