The Omron K8AK-VS3 100-240VAC is a voltage sensing relay with a trip range covering 20 to 600V AC/DC, making it suitable for monitoring under/over-voltage conditions on DIN rail-mounted control panels. Adjustable delay from 0.1 to 30 seconds prevents false tripping on voltage transients, and the SPDT output relay switches up to 5A at 250VAC for alarms or contactor control.
