Fibre Optics Fieldbus Isolating Repeater
Series 9186
> Easy installation and mainetance due to:
– Inherently 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

The Fibre Optic Isolating Repeater is used to build-up fibre optic network structures
in hazardous areas. It enables to transmit Profibus DP or Modbus signals over distances of up to 2 km or 1,2 miles. The optical interfaces are designed to be inherently
A3
safe (Ex op is). The protection scheme Ex op is allows to apply usual standardized
industry connectors. The Zone 1 / Div. 2 version of the Fibre Optic Isolating Repeater
offers an intrinsically safe RS-485 interface acc. to the standard RS-485 IS (PNO).

Critical levels of the received optical signal are detected by the integrated diagnostic
function. The fault is indicated by LEDs on the front side of the device and in addition
by a line fault contact. The contact is used to trigger a remote fault indication in the
control room. The diagnostic function enables preventive maintenance and
improves the availability of the plant.
