Product Overview

The RS204 (Order Number: 00012220-00) is a high-performance communication expansion module for the Bachmann M1 automation system. It provides four independent, software-configurable serial interfaces within a single-slot housing, enabling the central processor to manage multiple peripheral device streams simultaneously. This module is essential for integrating legacy hardware, specialized sensors, or third-party controllers into the M1 ecosystem.

To ensure deterministic performance and data integrity in harsh industrial environments, the RS204 (00012220-00) features 500 V RMS galvanic isolation between the ports and the system bus. Its rugged Austrian-built design provides high vibration resilience, making it a reliable choice for mission-critical applications in the maritime, energy, and heavy industrial sectors.
