are designed to be used in optical PROFIBUS field bus
networks. They enable electrical PROFIBUS interfaces
(RS 485 level) to be converted into optical PROFIBUS
interfaces and vice-versa.
Table 1, p. 6 shows the different methods for connecting
the modules, and the maximum optical ranges of each
By profiting from the familiar advantages of optical transmission technology, the modules can be integrated into
existing PROFIBUS field bus networks.
A complete PROFIBUS field bus network with modules in
line, star or ring topology, and an arbitrary combination
of these, can also be built up.
The redundant ring is also supported, thereby increasing
the fail-safety of the field bus network.
Each module has two or three mutually independent
ports, which in turn consist of a transmitting and a
The device is powered by 24V DC voltage. A redundant
feed increases operational safety.
The electric port is a 9-pole Sub-D socket (female). An
RS 485 bus segment in line with the PROFIBUS standard
EN 50170 can be connected to this port.
The optical fibers are connected using BFOC /2.5 (ST®)
Four multicolored light-emitting diodes indicate the
current operating status and possible operating malfunctions.
One measuring output is available for each optical port
where the optical input level can be measured using a

OZD Profi 12M G12 and OZD Profi 12M G12-EEC have
the same function. They only differ in the specification
of the climatic ambient conditions: while the OZD Profi
12M G12 is suitable for employment in the standard
temperature range from 0°C to 60°C, the OZD Profi
12M G12-EECC (extended environmental conditions)
can be used in the extended temperature range from –
20°C to +60°C and at up to 100% humidity.
