RIBMNWLB-7-BC AHU Fan Safety Alarm and Logic Circuit, BACnet MS/TP, 7 Binary Inputs, 2 Binary Outputs, Track Mount (2.75 in.)
Open circuit board for air handler safety wiring: in its default mode, BO 1 closes only while all six alarm inputs (BI 1-BI 6) are closed, and BO 2 follows BI 7. Inputs have override and latching DIP switches with a clear-latches pushbutton. It can also be set up as a plain I/O board.
Key Features
- Logic: Fan Safety Circuit mode by default: BO 1 closes when BI 1-BI 6 are all closed; BO 2 follows BI 7. Can also run as an I/O board with 2 BO and 7 BI
- Inputs/Outputs: 2 BO (relays) with override; 7 BI; BI 1-BI 6 with override and latching DIP switches
- Power input: 24 VAC/DC, 50-60 Hz; 75 mA @ 24 VAC or 30 mA @ 24 VDC, plus the BO 1-1 load
