PSI-MOS-RS232/FO 850 T - FO converters

FO converter with integrated optical diagnostics, alarm contact, for RS-232 interfaces up to 115.2 kbps, T-coupler with two FO interfaces (BFOC), 850 nm, for PCF/fiberglass cable (multimode)

  • Supply voltage and data signals routed through the DIN rail connectors
  • Connections can be plugged in via a COMBICON screw terminal block
  • Redundant power supply possible by means of optional system power supply unit
  • High-quality electrical isolation between all interfaces (RS-232 // fiber optic ports // power supply // DIN rail connector)
  • Approved for use in zone 2
  • Intrinsically safe fiber optic interface (Ex op is) for direct connection to devices in zone 1
  • Integrated optical diagnostics for continuous monitoring of FO paths
  • Floating switch contact for advance warning of critical FO paths
  • Automatic data rate detection for all data rates up to 115.2 kbps
