Description
The Littelfuse KRD9220B Retriggerable Solid State W/Relay 2″ X 2″ is used to retrigger for controlled switching and timing in electrical control circuits. It offers adjustable timing, and restarts the timing cycle on reapplication of the input signal for repeated sequencing control. It is solid-state and therefore operates consistently and with fewer mechanical conventional relays than It is widely used in control panels, HVAC systems and industrial applications to control and coordinate the operation of electrical systems, ensuring efficient control of loads and sequences over time.
