Application

Scope of Application
The Sync.-Transceiver is designed as a component for the time synchronization of
numerical SIPROTEC protection devices in substations. The use with other devices in
further applications may work but is not tested by the manufacturer.
The Sync.-Transceiver converts optical input signals, for example telegrams or pulses
from a DCF77 or GPS-receiver, to electrical signals suitable for several SIPROTEC
protection devices to time synchronize this relays. The device has two independent
channels, which can be switched by a DIP-switch to different modes of operation.
For the connection to time receivers and SIPROTEC protection devices, corresponding
optical and electrical inputs and outputs are available, which can be configured
according to the selected application.
General data
The Sync.-Transceiver has a plastic housing that can be snapped onto DIN mounting
rail.
The auxiliary power supply is fed in via two screw terminals. Because of the wide
auxiliary voltage range (DC 24-250 V DC and AC 60-250 V), the converter can be
connected to all common types of station batteries and AC main voltage supplies.
The front cover has a green LED for the indication of the operating power supply and
two yellow LED for the indication of the data transfer.
By means of a potential free alarm contact an alarm can be indicated due to loss of
power supply or a failure of the power supply. When a fault condition is present, the
contact is closed.
Functional description of typical applications
The device has two independent channels, which can be switched together if
necessary. In the following, examples of typical application are described for both
channels in independent and combined mode.
Application for channel 1
Digital input signals at the fibre optic input (R1), a telegram or a single pulse, are issued
at the 24 V electrical outputs X1 at PIN 1 and PIN 3. The +24 V voltage output from the
internal power supply is direct connected with PIN 1. The ground GND (-24 V) is
switched to PIN 3 in light idle state ON at the optical input R1.
