X20BM11

X20BM11 is a B & R Automation bus module in the X20 Fieldbus Input Output Modules series. It operates as an active bus station, allowing it to participate directly in bus communication. Bus data contacts carry communication signals between connected modules, while bus supply contacts distribute power along the bus. The module requires 0.13 W of bus power for operation.

I/O supply contacts provide the electrical connection for input and output power. The I/O supply route is connected through, allowing this supply to continue across adjacent modules. A 24 VDC keying voltage supports correct voltage-group identification and helps prevent connection to an incompatible module group. Parallel power modules are supported, enabling additional power modules to be installed in parallel where the system configuration requires increased or separated power distribution.
