Description
The Littelfuse KRD9220B is a retriggerable single-shot time delay relay designed for precise and repeatable timing control in industrial and OEM applications. Featuring a compact 2" x 2" encapsulated design, it offers excellent stability, reliability, and resistance to shock, vibration, and humidity. This relay operates on 24VAC/DC and includes a retriggerable timing function—meaning the timing cycle resets and restarts whenever the initiate signal is reapplied. This makes it ideal for applications requiring continuous or extended timing control. The unit provides isolated SPDT output contacts for flexible control of connected equipment.
