1. Description
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 venti-
lation 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), de-
pending 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 F9 and
baud rates 9600 Bd, 19200 Bd, 38400 Bd, 57600 Bd, 76800 Bd
and 115200 Bd.
