D Line is ABB’s new range 
of digital time switches.
An exclusive design, featuring 
a backlit white LCD display, 
plus extremely simple use with 
two-line text menus and only 
four pushbuttons, make the 
D Line products ideal for 
automating the functions of the 
installation.

Thanks to the pioneering way in which vacation periods can 

be managed, the new D Line allows you to override the 

normal weekly program for one or more periods of the year or 

even through different years. The range includes versions with 

1 and 2 channels, equipped with large capacity internal 

batteries so they are able to function during a blackout and 

an EEPROM permanent data store, to ensure that the 

scheduled program is followed and the date and hour settings 

are maintained even during a power failure. 

The “PLUS” versions can copy one or more programs and 

transfer them to different devices by means of a flash drive, 

without wasting time and avoiding re-programming errors. 

The “SYNCHRO” versions can be combined with the D DCF 

antenna, allowing the circuit-breaker to be automatically 

synchronized with the DCF77 Frankfurt timing signal, or with 

the D GPS antenna, which synchronizes with the signal 

received by the Global Positioning System and provides a 

more precise solution than the terrestrial transmissions. These 

versions are required when one or more circuit-breakers need 

to be kept synchronized, even when installed in unattended 

areas.
