Omron K8AK-AS1 24VAC/DC Current Monitoring Relay – Single-Phase Over/Under Current 2–500mA AC/DC, 22.5 mm, 1×SPDT

The Omron K8AK-AS1 24VAC/DC is a precision single-phase current monitoring relay designed for detecting over-current and under-current in low-level AC or DC circuits. Ideal for sensitive load and sensor protection, it operates from a 24VAC/DC supply and offers a fine adjustable detection range from 2 mA to 500 mA. The slim 22.5 mm DIN-rail housing and 1×SPDT relay output make it easy to integrate into compact control panels and instrumentation systems.

Featuring front rotary dials, LED status indication, and reliable electromechanical output contacts, the K8AK-AS1 provides accurate current detection and system protection in automation, instrumentation, and process control applications.
