Bachmann BS204 Backplane Module – M200 Controller Hardware

Scalable Backbone for M200 Controller Platforms

The Bachmann BS204 backplane forms the structural and electrical core of every M200 automation system. I highlight its slot capacity, mechanical strength, and installation flexibility to deliver clear and SEO-ready technical content.

Modular Connection for Flexible M200 Architectures

The BS204 links power supplies, CPUs, and I/O modules through a stable and compact bus design. Each backplane supports between one and sixteen slots, and it snaps directly onto an EN 60715 DIN rail for fast system assembly. Bachmann also offers S201, S202, S203, and S205 adapters for standalone modules without an integrated backplane connection.
