Marine Master Clock is the ideal solution for distribution of both Local and UTC time on board ships. The Master Clock is equipped with several outputs and inputs for control of Slave Clocks as well as distribution of time to computers and other equipment needing the correct time. The four Slave Clock outputs  can be individually programmed for different types of clocks. External radio receivers / time synchronisation  sources can be connected when higher accuracy is needed.

The clock is also used for the control and regulation of various energy consumers such as electrical striking plates and buzzers for pause  signalling. The master Clock has a built-in yearly programmer with two relay outputs.

The Master Clock is equipped with 10 buttons and a 2 x 16 character LCD. To facilitate the change of time zones, two of the buttons are dedicated to this purpose. A light dimmer makes it possible to adjust the  background-illumination to the surrounding light level.
