Namur Control Unit
Namur Control Unit is used with Namur sensors to convert the low current signal of the sensor into a relay switching action. It can be used with either the Inductive or capacitive Namur sensors. The Namur sensor is positioned in the hazardous area and is connected by two wires to this Namur control unit, which is to be mounted in a safe area or inside a flameproof enclosure. Three LEDs indicators on the front fascia of the unit indicate Power, Cable fault and Relay status.
