Bachmann BS204 4-Slot Backplane for CPU and I/O Modules

Product Overview

The BS204 (Model: BS204) is a high-integrity 4-slot backplane module engineered to provide the essential mechanical and electrical infrastructure for the Bachmann M1 automation system. This chassis facilitates the secure mounting and deterministic interconnection of CPU modules, power supplies, and various I/O or communication cards. By centralizing the distribution of 24 VDC power and high-speed bus signals, the BS204 (Part Number: BS204) ensures seamless data exchange across the controller architecture.

Designed for high-reliability industrial environments, the BS204 (Order Number: BS204) features robust shielding and galvanic isolation to protect logic signals from field-side interference. Its compact 4-slot design is optimized for modular scalability, allowing engineers to build high-performance control nodes in space-constrained cabinets for energy management, process control, and factory automation.
