Product specification
The BACnet MS/TP three-point module with 6 digital inputs, 2 two-level relay outputs and 2 digital outputs was developed for decentralized
switching tasks. It is suitable for switching, for example, multi-level pumps and fans or louvers. In this case it is necessary to protect the relay
contacts by appropriate load-dependent measures. The inputs and outputs can be switched and scanned by means of standard objects via a
BACnet client. The input terminals 1 to 6 are wired with the C2 terminals on two poles to potential-free switches or contacts. The module has a
manual control for the outputs. The module address and the baud rate are set by means of two address switches on the front. Suitable for
decentralized mounting in serial sub-distributor.
• Connection with spring clamp terminal blocks (push-in)
