OP41 OP42 OP43 TDR Series Octal Plug-In

Time Delay Relay

The ICS OP4 Series time delay relay offers either an on, off, or interval time delay in a self-contained enclosure. The base configuration for the OP41/43 relay is 8 pin octal plug-in and the OP42 relay is 11 pin round plug-in. Both include DPDT Form C contacts.

Available in standard and nonstandard voltages and time delay ranges, the OP4 can be used in many applications requiring a time delay relay. Use the table below to select your relay action, time range, and input voltage. In addition to the listed values, special or custom time delay ranges are also available. *The OP4 TDR Series also includes the recycle timer relay.
