Multifunction time delay relay REV-120 is a 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;
  • selectable time range from 0.1 s to 1 hour.

Additional Information:

  • Item Code: REV-120
  • Port of Dispatch: New Delhi, India
