Real Time Clock for A850

The A850 Telemetry Gateway requires for proper functioning that date and time are set. When main power fails for such a long time that even the internal battery pack of the A850 gets fully drained, the A850 looses all volatile settings - date and time. Once power comes back, this RTC module will provide both, date and time, to the A850, and enable it to continue operation where it left off when it shut down.

This RTC module is based on a Texas Instruments Real Time Clock chip with integrated Lithium Battery, that will ensure at least a 10 year lifetime of the battery without mains power. Accuracy is much better than 1 minute per month. This module can easily be retrofitted into older A850 units that were purchased before Adcon equipped all units with this module (~ March 2013)
