Omron K8AK-AS2 24VAC/DC Current Monitoring Relay – Single-Phase Over/Under Current, 0.1–8A AC/DC, 22.5 mm, 1×SPDT

The Omron K8AK-AS2 24VAC/DC is a single-phase current monitoring relay designed to protect electrical equipment against over-current and under-current conditions in both AC and DC systems. With a slim 22.5 mm DIN-rail housing, wide adjustable range from 0.1A to 8A, and a universal 24VAC/DC power supply, this monitoring relay ensures precise and reliable protection for motors, pumps, and industrial control circuits.

Equipped with a 1×SPDT relay output and LED status indicator, the K8AK-AS2 provides clear operational feedback and simple configuration through front-mounted rotary dials. It can also be paired with an external current transformer (CT) for higher current monitoring, making it ideal for flexible integration in automation systems.
