Description
The Bachmann FM211 Fastbus Module is a high-performance communication module designed for distributing substations over long distances with minimal signal delay. It is part of the FASTBUS family, which includes master modules with 1 or 2 fiber optic (FO) interfaces and slave modules with or without integrated power supply, enabling seamless substation networking.

The FM211 supports connection to multiple distributed substations, with distances of up to 40 m for POF cables, 150 m for standard HCS cables, and 180 m for special HCS cables between two stations, and a total network length of up to 1000 m. It allows integration of up to 15 distributed substations for efficient and reliable automation control.

This module operates on a 24 VDC input (range 18–34 V) and features an integrated power output supporting I/O modules, including +5 V (2800 mA), +15 V (250 mA), and –15 V (200 mA). The FM211 provides galvanic isolation of 500 V from the system, ensuring safe and robust operation in demanding industrial or marine environments.

Designed to meet international standards, the FM211 complies with CE, cULus, CCC, and marine certifications such as DNV GL, LR, ABS, BV, NK, KR, RINA. It supports a wide operating temperature range from 0–60 °C, storage temperature from –40–85 °C, and relative humidity of 5–95%, ensuring reliable performance in diverse environmental conditions.
