750-640

The 750-640 RTC Module provides the higher-level control system with the actual time. The time is buffered and continues to run in the event of a power failure. When an external receiver is connected, the clock can be set using the time signal from DCF77, WWVB, or MSF. By default, the module is set to receive DCF77 signals. The receiver can be supplied directly via the module. Connecting an external receiver to operate the RTC module is not absolutely necessary. With its 32 channels, the integrated time switch clock function makes it easier for the control unit to process time-triggered actions. The module also counts the power-on time of the 32 channels.
