The EuroTime Center ETC operates conventional clock systems with impulse controlled slave clocks as well as modern, self-setting MOBALine installations. Easy and intuitive operation control due to ETC's intelligible user interface. ETC's power relays control light, heating, signalling-bells and other devices by weekly periodic and/or date related programs. Absolute precision of ETC's internal clock can be achieved by synchronization to an external time-reference such DCF77 or GPS.

Programming the switching circuits on a PC

Optional software running in the familiar WINDOWS environment enable even complex switching and signalling programs to be produced in a clear way and then loaded in the master clock via the serial interface.
