The CM-ENS.23P is a relay from the CM family for level monitoring and level control. The rated control supply voltage is 110-130 V AC, or 220-240 V AC. 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. The operating principle and sensitivity can be set using potentiometers on the front. Various electrodes and a sealable transparent cover to protect against unauthorized adjustment of the settings are available as accessories. The device has maintenance-free and easy-to-use push-in terminals.
