The Omron K8DT-AW1CA is an active-production current sensing relay that monitors AC or DC current from 2 to 500 mA, with an adjustable delay from 0.1 to 30 seconds. The SPDT (1 Form C) relay output can switch 5 A at 250 VAC, suitable for alarm, shutdown, or feedback circuits in control panels. Supply voltage is fixed at 100–240 VAC; the unit mounts on a DIN rail. The trip point is set via a potentiometer over the 2–500 mA range, and the trip delay is independently adjustable. For overcurrent or undercurrent detection, this relay provides a single SPDT changeover contact — no fieldbus or analog output, just a clean dry contact for the PLC or annunciator. The 5 A contact rating handles most intermediate relay coils or signal loads without an interposer.
