The large display DU70 is a 50mm hight LED matrix display that shows time and date 16 character wide as follows: day of month, month, hours, minutes and seconds. It is available as a free running stand alone clock, as a slave clock or as a radio clock with integrated DCF77 receiver.

* After powering up the system the time keeped in the real time clock is displayed immediately. A dot between the date and the time on the display indicates that the clock is running free. After synchronisation this dot dissappears, however, after loss of reception for more than 6 hours the dot appears again.

The DCF variant provides automatic changeover of daylight saving. In case of supply voltage failure the on board RTC keeps the time based on XTAL (quartz crystal) for at least 10 years. English or German can be choosen as display language. The wall mounted housing of the DU70 is made of plastic coated steel sheet.

The power connector, the antenna input and the RS232/20mA interfaces provided by DU70 are accessible via connectors in the rear panel of the case.

The requested supply voltage is applied via the power cord receptacle in the rear panel. After connecting the power cord and the antenna (only DCF variant) the system is ready to operate. Time and date become visible on the display.
