Product details

DIN-rail current monitor for motor and heater circuits

The Omron K8DT-AS2CA is a DIN-rail-mount current sensing relay that monitors AC or DC current from 0.1 A up to 5 A, with an adjustable trip delay from 0.1 to 30 seconds. It outputs a SPDT relay contact rated 5 A at 250 VAC, powered by a 100-240 VAC supply. This is the part you spec into a panel when you need to detect an undercurrent (belt slip, pump dry-run, heater element failure) or overcurrent (jammed conveyor, stalled motor) and trigger an alarm or shutdown.

Trip range and delay: what they mean on the line

The 0.1-5 A AC/DC trip range covers small motor FLA, heater bank draw, and solenoid currents. The 0.1-30 second adjustable delay lets you ignore inrush — a motor starting transient.

Frequently asked questions

What is the K8DT-AS2CA trip current range?

The trip current range is 0.1 to 5 A AC or DC. You set the trip point within that window using the front-panel dial.

How do I wire the K8DT-AS2CA?

Power the unit with 100-240 VAC on the supply terminals. Pass the monitored conductor through the internal CT aperture (or connect via the current input terminals, depending on model variant). The SPDT relay output connects to your alarm or control circuit. The push-in terminals accept solid or ferruled stranded wire without screw clamping.
