The Omron K8DT-VW3CA is an under/over voltage sensing relay from the K8DT series. It monitors AC or DC voltage between 20 and 600V and switches a single SPDT relay contact rated 5A at 250VAC. An adjustable delay timer (0.1 to 30 seconds) is built in to ride through momentary dips or surges, preventing nuisance trips on transient events.
