Typical application area for the FO-Repeater is communication of the protection data
interface of 7SD52, 7SD610, 7SA52 and 7SA6 differential and distance protection devices.
Furthermore, serial data of the 7XV5 device series can be transferred over long distances.
The connection to the protection device is provided interference-proof by means of a fibre-
optic connection. The maximum optical transmission distance between the protection device
and FO-Repeater is specified to 1.5 km, when a 62.5/125 µm or 50/125 µm fibre-optic cable
is used.
The FO-Repeater supports easy commissioning of the entire communications path. The
loops for port 1/2 can be activated for commissioning so that the input signals are mirrored
on the respective port. The repeater has a relay contact to output a “device ready” signal
(DR) and has also a wide range power supply unit covering the entire normal DC and AC
auxiliary voltage range.
Note:
The operation with bidirectional FO-Repeaters offers the advantage that only
one fibre-optic cable is required for transmission in both directions. For this
purpose one device each is required with the order options - 0BL00 and
0BK00 (see ordering data). Devices with the same ordering numbers must
not be used in pairs.
