Star coupler - mcFO-ST with mcPS-1

mcFO with mcPS-1

Modular and flexible

Many users can be integrated by bundling several FO signals on one RS-485 bus. The system consists of an mcPS-1 power supply module and up to ten mcFO fibre optic modules with two fibre optic ports each.

The mcPS-1 power supply module has an integrated RS-485 connection for coupling the transmission protocol and supplies the connected fibre optic modules via bus connectors. It is possible to physically couple up to 30 further star coupler groups at the RS-485 interface.

Application areas

Typical application areas of the media converter include

  • Substations and large transformer stations
  • Switching stations
  • Gas transfer stations
  • Bridging explosive hazard zones in industrial plants
