Overview
1SVR740850R0300 — CM-ENS.31P Liquid level monitoring relay, a level monitoring relay, liquid level monitoring, liquid level monitors from the ABB CM-ENS.31P – 24-240V AC/DC, dry running and overflow protection range.
The CM-ENS.31P belongs to the CM liquid level monitoring relay range. It operates with a rated control supply voltage of 24 – 240 V AC/DC and has a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A. It monitors liquid levels of conductive fluids and protects pumps against dry running or tanks against overflow. The working principle as well as the sensitivity can be selected via front-face potentiometers. Furthermore, an ON-delay or an OFF-delay can be adjusted within a range of 0.1 to 10 s. Several electrodes and a sealable transparent cover for protection against unauthorized changes are available as accessory. The device offers maintenance free Easy Connect Technology with push-in terminals.
