Glass fiber technology
The use of glass fiber transmission technology enables
a very large transmission range and ensures optimal
protection from EMC effects on the transmission path
and – due to the potential separation – on the Repeater
itself.
Power supply
The power supply is +24 V direct current. To improve the
operating safety, a redundant operating power supply
consisting of two separate sources can be used. For this
purpose, you must connect the two operating voltages to
two different terminals of the 7-pin screw-type terminal
block.
Both connections are uncoupled by means of diodes to
prevent reverse voltage supply or destruction through
incorrect pole connection.
There is no load distribution between the sources. With
redundant supply, the power supply unit with the higher
output voltage must supply the repeater alone.
Signal contact
A signal contact (relay with unconnected contacts) is
used to signal various disruptions in the repeaters.
The signal contact is also connected to the 7-pin screw-
type terminal block.
Measuring output
One measuring output is available for each optical chan-
nel at the 3-pin screw terminal block on the front of the
repeater.
LEDs
Four multicolored light-emitting diodes indicate the
current operating status and possible operating mal -
functions.
Configuration
You can easily set the configuration to meet your specific
requirements by means of DIL code switches, which can
easily be operated from outside.
The following settings are possible:
䡲
Compatibility to OZD Profi …a version
䡲
Operating mode
䡲
Reducing the optical transmitting power
