The Omron K8AK-AS1 24VAC/DC is a current monitoring relay in the K8AK-AS series. It operates on a 24 VAC/DC control supply and provides a single 1CO (SPDT) contact rated 5 A at 250 V AC or 30 V DC. The monitoring range spans AC from 2 mA up to 200 A, and DC from 2 mA to 8 A, making it suitable for detecting overcurrent, undercurrent, or phase loss in motor circuits, heaters, or general load monitoring. Housed in a standard 22.5 mm wide DIN-rail enclosure (IP20), it fits tightly into small control panels and uses screw terminals for wiring 5 A control circuits. Frequency range is 45–65 Hz.
