ABB CM-ENS.23S LIQUID LEVEL MONITORING RELAY 0.1-1000kΩ 3 ELECTRODES CONTROL 110-130 VAC/220-240 VAC 1CO

The Liquid Level Monitoring Relay is designed for filling or draining monitoring. It has a measuring range of 0.1 to 1000 kohm and uses three electrodes. The relay operates with a rated control supply voltage of either 110-130 V AC or 220-240 V AC. It features a 1 CO (SPDT) output and double-chamber cage connection terminals. This relay is specifically designed to monitor liquid levels of conductive fluids. It provides protection against dry running for pumps and overflow for tanks. The relay can operate according to the open- or closed-circuit principle, depending on the desired working principle and sensitivity. To adjust the working principle and sensitivity, simply use the front-face potentiometers provided.
