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
