Model mcFO with mcPS-1 -Fibre Optic Module Bundle
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
Modular star coupler/media converter EIA/RS-485 on FO consisting of mcPS-1 power supply module and up to 10 FO modules with 2 FO ports each
mcPS-1 power supply modulePower supply module, 24-60 V DC ± 20 %, 20 VA; allows operation with up to 10 mcFO fibre optic modules
