Program master clock M+S

General
The program master clock is a combination of an annual program clock with 8 outputs for controlling various energy consumers and a master clock for operating slave clocks with 2 pulse outputs.

It has a preprogrammed annual calendar/almanac with the year’s public holidays already entered.

The type of communication that synchronize the slave clock is chosen in the master clock, e.g. 24 VDC pole-switching minute impulses, Time code or NTP if the Ethernet card option is built into the master clock.

For extra accuracy, an external signal receiver e.g. GPS can be connected to the master clock.

Power failure
In the event of a power failure, the master clock retains its settings for up to 72 hours. If power is restored within this period, the master clock automatically resets all clocks in the system.

Relay outputs
A total of 800 control functions can be programmed across 8 outputs. Repeating a daily function on a given output requires only 1 control function.

Further relay outputs (total 64) can be added by supplementing the program master clock with one or more expansion units.
