Functional Devices RIBMNLB-4 Board 322838-753 Color-Coded Ports: Clear identification of

Color-Coded Ports: Clear identification of P1 (high) and P2 (low) inlets reduces error during sample line connection

The resilient base mounting reduces vibration transfer

Negative Pressure Compatibility: Specifically ported for use with negative pressure burner systems requiring 1/2 PSI max inlet

provided the air handler unit is certified for multi-poise installation and the minimum CFM requirements are met to dissipate the 5KW load

this 3/4 HP motor operates at a fixed speed of 1100 RPM

Functional Devices RIBMNLB-4 Board 322838-753 Color-Coded Ports: Clear identification ofThe 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,
