CM-ENS.31S

General Information

  • Extended Product Type:
    CM-ENS.31S
  • Product ID:
    1SVR730850R0300
  • EAN:
    4013614502910
  • Catalog Description:
    CM-ENS.31S Liquid level monitoring relay 2c/o, sensitivity 0.1-1000kOhm
  • Long Description:
    The CM-ENS.31S 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 screw connection technology with double-chamber cage connection terminals.
