AVT5022 A

The design of the clock synchronized with the atomic time-model DCF77 controlled by the ATMEGA8535 processor.

Basic parameters:

• Displaying time in the format: hour, minute, second.
• Displaying the date in the format: day, month, year.
• Alarm clock 1 working in everyday mode, i.e. activating the alarm signal regardless of the day of the week.
• Alarm clock 2 automatically ignoring Saturday and Sunday as holidays and school days.
• Regardless of the acoustic signal generation, both alarm clocks control the relay to which devices with significant power consumption can be connected.
• Timer operating in the range from 1 second to 59 seconds, 59 minutes and 99 hours. The timer controls the second relay with a high contact load capacity.
• A stopwatch with a counting range identical to a timer.
• Data is entered into the clock using a six-button keyboard. We can change the time manually at any time.
• The clock can be equipped with an emergency power source which, when the power supply fails, supplies power to the processor alone.
• The information is presented on typical seven-segment LED displays with standard dimensions, additionally without any modifications, you can equip the system with displays with a height of 57mm.

The system, although it is intended for permanent cooperation with the DCF77 receiver ( AVT217 / 1 ), can also work as a regular clock synchronized with quartz.

The printed circuit board and documentation are included.

ATTENTION!!! The DCF77 receiver is not included - you must purchase it separately.

A version with a set of independent components is available
