DCF RADIO RECEIVER

The GM14 radio time synchronisation receiver enables the time synchronisation of Grayson master clocks, to DCF radio time code signals.
DCF transmits from GERMANY. You will need to offest your master clock by an hour.
The DCF carrier is interrupted every second to encode time and date information with a full time, date and status message being transmitted every minute.
The length of the individual carrier breaks determine the value of the coded information and the time of transmission within each minute determines the identity of each bit. Installation of a radio receiver on your system will provide you with very accurate time and date information, together with automatic summer and Winter time changes.

Time signals inputs:

• DCF long wave signal from Frankfurt

Time signals outputs:

• DCF current loop

Time signal accuracy:

• Typically +/- 20 ms

Cable:

• Antenna to master clock: 10m signal cable as standard. Up to 200m available to order.
