DLC-4U-M-2W Level Controller gets signal from each point of the sensor installed in the tank and displays the level of the liquid in the tank with its LED points.
As a 2-wire-type controller, the controller is responding only to its compatible level sensor's current output which was converted from its original contact switching signal, by the sensor's current converter.
LED display enables you to read the current status correctly and easily.
