Functional Devices RIBMNLB-4 Board 30067439-890 heavy oils often produce aThe Functional Devices RIBMNLB 4 logic board is a field proven AHU fan safety alarm circuit designed to aggregate multiple shutdown signals into a single supervisory point. This 4 input logic module eliminates the need for complex, hand wired relay interlocking by using high density 2. 75 inch track mount housing. Optimized for 24Vac dc power input, the board accepts up to four normally closed (N C) inputstypically from smoke detectors, freeze stats,
