  SICLOCK DCFRS wireless receiver (without antenna base)

  SICLOCK DCFRS wireless receivers receive signals from the DCF77 time signal transmitter. The DCF77 transmitter is located in Mainflingen near Frankfurt am Main and transmits long-wave signals at a frequency of 77.5 kHz. Under good reception conditions, signals can be received within a radius of up to 1 500 km of the transmitter location.

  Unlike devices that receive signals from satellites, the SICLOCK DCFRS can also be used inside buildings. SICLOCK DCF77 wireless receivers output the demodulated DCF77 time signal.

  SICLOCK DCF77 wireless receivers are available in two versions:

  • SICLOCK DCFRS with TTY interface (20 mA current interface) for direct connection to central plant clocks
  • SICLOCK DCFRS with RS 232 signal level for connection to PCs

  Note:

  We recommend the software DCF77 receiving service (Article No. 2XV9450‑1AR28) if the RS 232 version is used, see "Accessories". Parameter assignment is not necessary for both receiver versions.
