Interface with fibre optic connection
Actuators for ordinary surroundings (Non EX) may have an extended compact plug to incorporate a special
fibre optic interface board. The connection of the fibre optic cables to the interface board is shown in the
following picture:
Fibre optic connection inside the compact plug
The connector for the fibre optic wires is the one of type F-St. The core of the optical fibres might be of
diameter 50µm or 62.5 µm. To connect the fibre optic cables, open the cover of the extended compact plug.
Using the maximum of four cable glands (M20x1.5) the cables can be inducted into the housing. Connect the
optical fibres to the appropriate plugs: Connect the output of a device with the input of the other one and the
input with the output. The board provides an active connection between inputs and outputs. By default the
converter board is powered by the electronic unit. Thus in case of a power failure the communication to the
rest of the slaves connected to the output of the device is lost. This effect can be avoided by additionally
powering the electronic unit with external 24 V DC
