True Off Delay Relay

OP4 Series TDR Timing Actions Voltage Sensor OP4 Series Recycle Relay

An ICS true off delay relay is an off delay relay that provides a relay contact for a preset delay period after voltage is removed from the input terminals A and B. When the input voltage is removed, the off countdown timer begins. At the completion of the delay cycle, the relay is de-energized and the contact transfer is made.

The off delay period of the internal control circuit is externally adjustable by means of a calibrated-dial potentiometer. The case style is standard 11 pin blade base. External contact is SPDT. The ICS K7830 and K7835 single phase true off delay relays are both UL and CSA Listed and carry a one year warranty against defect.
