Product details

Current Sensing Relay for AC or DC Branches

The Omron K8DT-AS2TD is a current-sensing relay for AC or DC systems, adjustable from 0.1 up to 5A, with a solid-state NPN output and a configurable delay between 0.1 and 30 seconds.

Trip Range and Delay – Setting the Operating Window

The trip range of 0.1 to 5 A AC/DC covers small motor loads, heater currents, and DC drive circuits. Set the potentiometer to the nominal running current; the delay timer then filters out startup inrush or short transients up to 30 seconds. Because the output is a solid-state NPN (sinking) device, it interfaces directly with a PLC digital input or an alarm module – no interposing relay needed. Verify your input card sinks or sources correctly.

Frequently asked questions

What type of current does it sense – AC, DC, or both?

It senses both AC and DC current, with a trip range of 0.1 to 5 A.

What is the output type and logic?

The output is a solid-state NPN (sinking) switch, suitable for driving PLC inputs or alarms within its rated supply voltage.

What is the delay time range?

Adjustable from 0.1 to 30 seconds, set by a front-panel dial.

Does it mount on a DIN rail?

Yes, the K8DT-AS2TD is designed for standard DIN rail mounting.
