The CM-ENS series consists of liquid level monitoring relays designed for controlling conductive fluids in applications such as overflow protection, dry-running prevention, and min/max level alarm systems. The relays feature a compact housing 22.5 mm wide with UL 94 V-0 flame rating, and support two wiring technologies: screw terminals and Easy Connect Technology. They operate on a wide range of supply voltages from 24 to 240 V AC/DC, include two SPDT contacts, and offer adjustable sensitivity and response delays via front-mounted potentiometers. Three LEDs indicate operational states including power, relay status, and electrode condition. Tool-free DIN rail mounting and environmental robustness for high vibration and electromagnetic interference are standard across the series.
Liquid Level Monitoring Relays
High performance monitoring of levels
ABB's liquid level monitoring relays are used for regulation and control of liquid levels and ratios of mixtures of conductive fluids. The assortment includes single function and multifunctional devices which can be used for overflow, dry-running protection of pumps, filling and draining applications as well as max. and min. level alarm. A range of accessories like different electrodes complete the offer.
