Functional Devices RIBMNWLB-7-BC : AHU Fan Safety Alarm and General Purpose Logic Circuit, BACnet MS/TP Network, 24 Vac/dc Power Input, Two Binary Outputs + Override, Seven Binary Inputs, 2.75″ Track Mount
RIBMNWLB-7-BC is a valuable space saver on your DDC controller by communicating which device is tripped over bacnet. This logic board has an additional input allowing for fan status to be communicated over the bacnet connection. All the safety devices are still hardwired to the safety shutdown circuit, so even in the event of a loss of communication the logic board will still shut down the air handler during a fall condition.
