1. Description

The BACnet MS/TP module with 4 digital outputs is designed for
local switching operations. It is suitable to operate electrical
components such as motors, contactors, lamps, sun-blinds etc. We
recommend to protect the relay contacts additionally by a
RC-element or high inductive loads. The module is provided with
a manual control facility for manual switching of the relays. The
outputs can be operated 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.
