4 ÷ 20MA GAS ANALYSIS MODULE WITH RELAY

Cooper CIT420R addressable 4-20 mA interface The CIT420R 4-20 mA addressable interface is compatible with Cooper analog addressable control units. This interface has a unique address on the loop. Each relay is programmable with its own sensitivity level that can be expressed as a percentage of L.E.L (Explosion Limit Level) or PPM (Parts per million) through the arrangement of DIL microswitches. Installation Separate the two halves of the unit Drill (or eliminate) the necessary cable entries in the surface-mount recessed box Mount the rear box in place and run the wires through it Connect the unit according to the diagram below Set the required threshold levels using the DIL switches
