Bulletin KR Series Specification

Ice Cube Relay with Fixed Time Delay

The ICS KR Series Cube Relay with fixed time delay is a low-cost solution for your design. Timing action and input voltage options combined with economy and durability make the KR Series Relay an excellent choice for an extensive variety of applications.
The embedded microcontroller-based circuit provides precision timing as well as excellent repeatability. Standard timing action options include delay on make (on delay), delay on release (off delay), repeat cycle (recycle) and interval delay. Input voltage selection covers commonly applicable AC and DC values. Custom models can be built to suit your requirement with quantity pricing available. Also availbale is the potted black box ICS KB Series Relay with adjustable delay.
