The BACnet MS/TP module with 10 digital inputs is designed for local switching operations. It is suitable to record potential-free switching states as for example electrical limit switches of ventilation valves or auxiliary contacts of power contactors. The inputs can be operated as contact and voltage inputs (A1, 24 VAC/DC, jumper J - A2) or with actuation to GND (A2, jumper J - A1), depending on the setting of the jumper J. The inputs can be scanned by standard objects 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 99 and baud rates 9600 Bd, 19200 Bd, 38400 Bd and 76800 Bd.
