OP45/46 Specification Actions True Off Delay KG Series OP4 Delay 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 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.

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

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

Notes. OFF Time is first in the OP6 Series order code.
OFF Time cycles first when voltage is applied.
