Current sensing relay for over/under monitoring
The K8DT-AW2TA is a current-production current sensing relay from Omron's K8DT series. It monitors AC/DC current from 0.1 to 5 A with an adjustable trip threshold and a delay time of 0.1 to 30 seconds. The NPN solid-state output sinks to a PLC input without extra interface hardware. Supply voltage is 100-240 VAC, so it fits any control panel worldwide. For the storeroom, this is a single SKU that covers a broad range of motor protection and load-monitoring applications. It's active, so no end-of-life worries for your BOM.
Mounting and supply
Mounts on standard DIN rail. The enclosure is compact, leaving room for other components in the gland plate area. No derating for ambient within that range is specified, so treat it as full-rated. The trip range and delay are set via front-panel dials; no programming tool required.
