ABB 1SVR730850R2200 CM-ENS.23S 1CO 0.1-1000kOhm 110-240V AC (Fill)Level Monitoring Relay

The ABB CM-ENS.23S (SKU: 1SVR730850R2200) is a liquid level monitoring relay from the ABB CM Series, designed to detect and control fill levels in tanks and vessels using electrode-based conductivity sensing. With an adjustable sensitivity range of 0.1 to 1000 kOhm and a single changeover (1C/O) output contact, the CM-ENS.23S provides reliable, interference-resistant level detection for industrial automation and process control applications operating at 110–130 V AC or 220–240 V AC.
