The Omron K8AK-VW3 24VAC/DC is an under/over voltage relay with a sensing range of 20 to 600 V AC/DC and an adjustable delay of 0.1 to 30 s. SPDT relay output (5 A at 250 VAC) directly drives a contactor coil or a PLC input. Supply the unit itself from 24 VAC/DC, making it easy to drop into an existing control transformer or DC bus. Operating temperature from -20°C to 60°C covers most pit-side cabinets without derating.
