The Bachmann FS211/N FASTBUS module is specifically engineered to facilitate the distribution of substations over extended distances while maintaining a very low signal delay. Additionally, the power supply integrated into the FASTBUS slave modules, like the FS211/N, can power the I/O modules of a substation.

Key Features

• FASTBUS master modules with 1 FO interface
• FASTBUS slave modules with 1 FO interface
• FASTBUS slave modules equipped with an integrated power supply
• Support for up to 15 distributed substations
• Distances between 2 stations:
  • 40 meters for POF (Plastic Optical Fiber) cables
  • 150 meters for HCS (Hard Clad Silica) cables
  • 180 meters for special HCS cables
• Status display (RUN/ERR) and a display for fiber type
• Minimal signal delay
