Liquid level control relay 24 VAC

The ENW-E12 Liquid Level Control Relay is designed to monitor the fill or leakage levels of conductive non-combustible media. It features an adjustable trigger via a proportional potentiometer. The device operates with electrodes for minimum and maximum levels, protecting submersible pumps from overfilling or running dry. It can also be used as a two-level controller to automate filling and emptying of containers. The device supports models with a supply voltage of either 230 V AC or 24 V AC.
