Bulletin 690 OP45/46 Series Relays

Recycle Timer Relay

The ICS OP45 recycle timer relay alternately produces closed and open conditions of the relay contacts with the duration of each condition equal in time, for example: 10 seconds open and 10 seconds closed. The delay period between alternations is adjustable by means of a single potentiometer.
The dual-adjust OP46 recycle timer relay also provides alternating closed and open conditions of the relay contacts. Time duration of each condition is independently adjustable, for example: 2 minutes closed and one minute open. When power is applied to the relay, the recycle timer action begins and continues until power is removed. OFF Time cycles first at power-up.
