Functional Devices RIBMNLB-6 Logic Board 319825-402 taper and 1/2" x 1/4"The Functional Devices RIBMNLB 6 is a 6 input logic board designed for high reliability AHU fan safety alarm circuits and general purpose logic applications. This track mount device streamlines complex relay logic by integrating six normally closed (N C) inputs that control a single master relay. When any of the monitored inputs openwhether from a low temperature alarm, smoke detector, or high pressure switchthe master relay trips, providing an
