Fibre Optics Fieldbus Isolating Repeater for Installation in Zone 1 Type 9186/12
Fibre Optics Fieldbus Isolating Repeater for Installation in Zone 1 Type 9186/12
  • Easy installation and maintenance due to:
    • Intrinsically safe optical interface
    • Intrinsically safe bus connection via RS 485 IS (PNO)
  • High availability due to:
    • Build-up of ring structures, redundant Point-to-Point , line structures
    • Integrated analysis of optical input signal
    • Error message if critical levels of input signal reached
  • Transmission of Profibus DP, Modbus, HART on RS 485, R. STAHL Servicebus
