Bulletin KB Series Relay Specification

Time Delay Cube Relay with Adjustable Timing

The ICS KB Series Time Delay Cube Relay is an economical, reliable and durable relay that is suitable for a wide variety of applications. Relay contacts provide up to 15 Amp current-handling capacity at 240VAC. The time delay is adjusted with a trimmer potentiometer. Two mounting holes on the case flanges are provided. Barrier terminal blocks with clamp screw terminals make the wiring connections easy and fast.
Microcontroller-based circuitry allows precise timing with outstanding repeatability. Common timing actions include delay on break (off delay), delay on make (on delay), repeat cycle (recycle) and interval delay. Numerous input voltage options and time ranges are available. Custom models can be defined to fit a particular application.
