BMT-F-TO4 BACnet MS/TP
Description
The BACnet MS/TP module with 4 digital triac outputs was developed for decentralized switching tasks. It is suitable for switching electrical components, such as relays, contactors, HLK valves, etc. The outputs can be switched by means of standard objects via a BACnet client. In addition, the outputs can be overridden manually by means of switches on the device. The module is addressed and the baud rate is set by means of two address switches on the front. Suitable for decentralized mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.
- Connection with spring clamp terminal blocks (push-in)

FAQ's
What can I do if the red ERROR LED on the module lights up or there is no communication?
There are several possible causes, please check the following:
- Operating voltage (A1 / A2) connected and sufficient for the device.
- BUS (A- / B+) connected and not reversed. Pay attention to (- / +), not to A/B.
- Address (rotary switches) set correctly, must not occur twice or be 0.
- Bit rate (rotary switches) set correctly, only possible in programming mode (see mounting note).
- Shielded and twisted pair cable used.
- Termination resistor (120 Ω) set on both sides.
- Bias resistors available once on the BUS.
- Max Master as high as the number of physical master I/Os on the BUS.
- Max Frame high enough for all answers from participants to get through (BMT-RTR setting).
