Using a durable 244 LEDs matrix, the UNILIGHT MATRIX SIGNAL is able to display most of the common signal aspects used in railways.

The signal is operated in conjunction with a controller (PLC) which controls the selected signal aspect via a 10- pin cable. Of course, it is also possible to use a customer-specific set of signal aspects.

The brightness of the signal is adapted automatically to the light intensity of the environment. During dusk and night, the signal is dimmed significantly.

The connection of the signal to the power supply is protected against reverse polarity and against surge voltage up to 1000V. The rugged construction and the choice of high quality components ensure a very high availability rate.


  • The UNILIGHT MATRIX SIGNAL is almost maintenance-free
  • Possible areas of application for the signal are local traffic railways, trams, suburban and underground trains
  • Automatic brightness control
  • The power supply is protected against reverse polarity and voltage peaks of up to 1000 V
  • The UNILIGHT MATRIX SIGNAL with standard software is offered in different versions
  • Almost every signal aspect can be displayed
