1 Introduction
The fiber-optic FIP repeater OZD FIP G3 is designed
for use in optical FIP field bus networks. It permits
conversions of electrical FIP interfaces into optical
FIP interfaces and vice versa.
The repeaters can be integrated into existing FIP field
bus networks. OZD FIP G3 repeaters can also be used
to configure a complete FIP field bus network with
line or ring topology.
The mechanical structure comprises a compact, rigid
metal housing which can either be mounted on a top-
hat rail or on any flat base.
No adjustment is necessary during start-up.
Ports
The repeater has three mutually independent
channels (ports), each of which in turn consists of
a transmitter and a receiver.
Port 1 is a 9-pin Sub-D connector (male). Ports 2 and 3
are optical BFOC/2.5 (ST ®) sockets.
Power supply
The operating voltage is +24 V to +48 V DC.
A redundant power supply from two separate sources
is provided to increase operational reliability. The two
operating voltages can be supplied to two different
terminals of the 5-pole terminal block.
Both connections are decoupled via diodes in order
to prevent feedback or destruction resulting from
polarity reversal.
There is no load distribution between the sources.
With redundant supply, only the power supply unit
with the higher output voltage provides the bus
adapter with power.
Signaling contact
Various repeater malfunctions can be indicated via a
signaling contact (relay with floating contacts). The
connections of the signaling contact also terminate at
the 5-pole terminal block.
LEDs
Four two-color LEDs indicate the current operating
status and any malfunctions.
