Why Choose the ABB DY DCF77 Antenna?
The ABB DY DCF77 is an external DCF77 radio antenna for the ABB DY365 digital yearly time switch, designed to provide automatic synchronisation with the official DCF77 time signal transmitted from Frankfurt, Germany. As part of the ABB DY time switch accessory range, it enables accurate radio-controlled timekeeping for advanced scheduling and building automation applications.
When connected to the ABB DY365, the antenna receives the DCF77 long-wave radio time signal and enables the time switch to synchronise automatically. This helps maintain accurate date and time settings without requiring routine manual correction, supporting dependable execution of programmed yearly schedules.
The DY DCF77 is powered through the associated DY365 time switch and uses a nominal 12 V DC supply. Its wall-mounted external format allows the antenna to be positioned for effective radio reception while the DY365 remains installed inside an electrical distribution board or control panel.

Reliable DCF77 Time Synchronisation
The ABB DY DCF77 receives the official DCF77 radio time signal transmitted from Frankfurt and uses it to synchronise the connected DY365 automatically. This provides an accurate external time reference for programmed switching operations and reduces the need for manual clock correction.
Because the antenna is installed separately from the DIN-rail time switch, it can be positioned where radio reception is more favourable while the DY365 remains protected inside the electrical panel. This makes the DY DCF77 a practical accessory for installations requiring dependable radio-synchronised yearly time control.
Typical Applications
- DCF77 synchronisation of ABB DY365 yearly time switches.
- Commercial building time-control systems.
- Public and exterior lighting automation.
- Industrial scheduled switching systems.
- Building services and facility automation.
- Electrical installations requiring accurate calendar-based switching.
