GPS time / frequency synchronisation generator
Siemens Energy

The Synchronisation Unit is used for conversion of different standard time systems and different output formats in a SIMEAS R and DAKON usable format. The advantage is that a time adaptation will be done automatically (also after a outage of the auxiliary power supply), where ever the system is installed. This is only possible with the Sync.-Box 7KE6000-8H_2_ (with decoder for a Hopf-signal), which is connected to a GPS Hopf receiver with a simulated DCF77 signal.
Time synchronization is achieved via a special input of the processor module to which a synchronization box (7KE6000-8HA*) is connected externally. Depending on implementation, the synchronization box can pick up the time signal from various receiver types, for example, via a GPS, DCF77 or IRIG-B. Synchronization with a GPS signal is the usual method. This requires special receivers that generally output a modulated telegram (DCF77, IRIG-B). This time telegram is passed on to the synchronization box. (In Germany and neighboring countries the DCF77 signal can be received directly. In this special case, the synchronization box can be connected to a DCF77 receiver with an integrated ferrite antenna.)
