The BACnet MS/TP module with 4 digital inputs was developed for decentralized switching tasks. It is suitable for recording potential-free switch states, e.g. electrical limit switches on ventilation flaps or auxiliary contacts on power contactors. The inputs can be connected using potential-free switches or contacts as well as voltage inputs. The inputs can be queried using standard objects via a BACnet client. The module is addressed and the bit rate is set using two address switches on the front. Suitable for decentralized installation on TH35 mounting rail according to IEC 60715 in electrical distribution boards. Connection with spring-loaded terminals (push-in)
