The CM-ENS.11S 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 / 4A). It monitors and controls levels and mixing ratios of conductive liquids. It is used for filling and emptying applications, for dry-run protection of pumps and for signaling the status of the monitored level. Working current principle. The sensitivity can be adjusted using a potentiometer on the front. Various electrodes and a sealable transparent cover to protect against unauthorized adjustment of the settings are available as accessories. The device is available with double-chamber box screw terminals or push-in terminals.
