The FM211 (Part Number: 00012200-00) is a FASTBUS Master fiber optic communication module for the Bachmann M1 system. It converts bus signals into optical pulses for high-speed, long-distance communication with total EMI immunity, making it ideal for wind farms, power plants, and maritime automation.
The module supports deterministic 10 Mbit/s data transmission over HCS fiber up to 200 meters per segment and integrates seamlessly with Bachmann SolutionCenter for network configuration and monitoring.
| Parameter | Specification |
|---|---|

Used to bridge central processors with remote substations, including wind turbine base-to-nacelle communication and maritime engine room to bridge links, where EMI immunity and signal integrity are critical.
Is FM211 compatible with standard plastic optical fiber (POF)?
No. HCS fiber is required for distances up to 200 m and certified industrial operation. POF works only over very short distances.
How many slave modules can one FM211 control?
It can manage multiple daisy-chained FS211/N slaves; exact numbers depend on system cycle time and total I/O volume configured in Bachmann SolutionCenter.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
We have sourced Honeywell and Schneider parts here for two years. Every shipment arrives well-packaged with original factory seals intact. Clear communication and the best lead times in the industry.
