PSI-MOS-PROFIB/FO 850 E-SO - FO converters

FO converter with integrated optical diagnostics, coated PCB, alarm contact, for PROFIBUS up to 12 Mbps, T-coupler with two FO interfaces (BFOC), 850 nm, for PCF or fiberglass cable (multimode)

  • With coated PCB for increased resistance to salt-laden atmospheres
  • Connections can be plugged in via a COMBICON screw terminal block
  • Can be combined with the PSI copper repeater in a modular way using DIN rail connectors
  • Supply voltage and data signals routed through the DIN rail connectors
  • Automatic data rate detection or fixed data rate setting via DIP switches
  • High-quality electrical isolation between all interfaces (PROFIBUS // fiber optic ports // power supply // DIN rail connector)
  • Redundant power supply possible by means of optional system power supply unit
  • Approved for use in zone 2
  • Integrated optical diagnostics for continuous monitoring of FO paths
  • Intrinsically safe fiber optic interface (Ex op is) for direct connection to devices in zone 1
  • Floating switch contact for advance warning of critical FO paths
  • Suitable for all data rates up to 12 Mbps
  • Bit retiming for any cascading depth
  • Shipbuilding approval in accordance with DNV GL
