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.

Selecting OP46 Series RECYCLE TIMER RELAY
Order Code Example: OP4 6 A D 5
6 = recycle timer relay
      (dual adjustment)
A = .1 to 10 sec. OFF
D = 1 to 60 sec. ON
5 = input voltage = 240 Volt AC

Selecting OP45 Series RECYCLE TIMER RELAY
Order Code Example: OP4 5 E N 1
5 = recycle timer relay
      (single adjustment)
E = timer range = 1 to 60 minute
1 = input voltage = 120 Volt AC

Notes. OFF Time is first in OP46 timing range order code. OFF Time cycles first when voltage is applied on both OP45 and OP46 relays.
Options: Fixed and Special time ranges from .05 sec. to 10 hour
