The Bachmann BS204 is a compact, high-reliability 4-slot backplane module for the M1 automation system. It provides the physical and electrical foundation for hosting up to four M1 hardware modules, including CPU, power supply, and I/O units. Engineered in Austria, the BS204 ensures signal integrity and deterministic communication across the modular architecture, making it ideal for smaller control panels or localized I/O substations.

Can the BS204 be daisy-chained with other backplanes?
No, it is designed for standalone use in smaller M1 configurations. For more than four slots, use larger Bachmann M1 backplanes.
Does this backplane include an integrated power supply?
No, the BS204 provides the bus and mechanical support only. External M1-compatible power supply modules are required to energize the backplane and installed modules.
