1. Description The BACnet MS/TP module with 8 individually configurable resistance or voltage inputs is designed for local switching operations. It is suitable to record resistance or voltage values of for example passive and active temperature sensors electrical ventilation or mixing valves, valve positions etc. The inputs are universally configurable by standard object via a BACnet-Client. Addressing of the module and baud rate setting are done with the two address switches (x1 / x10) on the front. Possible settings are addresses 00 to F9 and baud rates 9600 Bd, 19200 Bd, 38400 Bd, 57600, 76800 Bd and 115200 Bd. Analog Input Module BMT-AI8 11088213 7603/899299-03 2.
