The BACnet MS/TP module with 4 digital inputs and 2 relay outputs with manual control level was developed for decentralized switching tasks. Suitable for e.g. accommodating light switches and window contacts in a room and switching two light strips or as a blind control. 2 motor-operated fire dampers can also be controlled. The relay contacts must be protected by suitable load-dependent measures. The inputs can be operated as contact or voltage inputs. The inputs and outputs can be switched and queried via standard objects using a BACnet client. The module address and bit rate are set using two switches on the front. Suitable for decentralized installation on TH35 mounting rail according to IEC 60715 in electrical distribution boards. Connection with screw terminals
