The CM-ENS.21S is a relay from the CM family for level monitoring and level control. The rated control supply voltage is 24 - 240 V AC/DC. Output: 1 changeover contact (250 V / 4 A). It monitors and controls levels and mixing ratios of conductive liquids. It is used for filling and emptying applications, for dry running protection of pumps, and for signaling the status of the monitored level. The operating principle and sensitivity can be adjusted using potentiometers located on the front. Various electrodes and a sealable transparent cover to protect against unauthorized adjustments are available as accessories. The device is available with double chamber terminal blocks or push-in terminals. EAN: 4013614502927.
