Omron K8AK-AS1 Single-Phase Over/Under Current Monitoring Relay, 2-500 mA, 100-240 V AC/DC

Omron K8AK-AS1 is a 22.5 mm wide single-phase current-monitoring relay for over- or undercurrent detection in the 2-500 mA range. It operates on 100-240 V AC or DC control supply with screw terminations and delivers one SPDT change-over output. Adjustable on- and off-delay times run from 0.1 s to 30 s, and DC-current hysteresis is included. Housing dimensions are 22.5 x 90 x 100 mm.
