The Omron K8DT-VW2CD is a voltage sensing relay in the K8DT series, monitoring AC or DC voltage from 1 to 150 V through an adjustable trip range and an independent 0.1 to 30 s delay timer. The SPDT output handles 5 A at 250 VAC, so it can directly drive an alarm or a control contactor without an interposing relay. The 24 VAC/DC supply is separate from the sensed circuit, which means the relay keeps control power isolated from the monitored line.
The K8DT-VW2CD provides an adjustable trip range of 1-150 V AC/DC and a delay timer of 0.1-30 s, with SPDT contacts rated at 5 A at 250 VAC. Mounts on DIN rail; operates -20°C to 60°C for indoor use without forced cooling; powered by 24 VAC/DC supply.
