DG-LED16x128-R

DG-EL16128P8-R - 16 X 128 LED Passenger Information Display

The DG-EL16128P8-R is a rugged LED passenger information display targeting metro, train and tram installations. This display is purpose-built for railway applications with a wide 8-38VDC input range power supply. The LED chip resolution is 8mm in horizontal and vertical direction.

The display is based on a 32-bit CORTEX-M3 microcontroller with dedicated firmware, which can be customized to meet the specific requirement of each project, including custom graphics elements and language support. Error and diagnostic codes can be used to monitor the health of the display and its correct operation. Furthermore, the electrical parameters of each LED can be checked to detect open connection, short to ground or short to supply.

Constant current LED sink drivers are used to drive high brightness SMD LED chip components to increase the reliability and ruggedness of the display. The LED matrix brightness can be controlled from 0 to 100% under software control or based on ambient lighting conditions. The display base is black for improving contrast. The LED area is covered by a laminated tamper proof safety glass.

Duragon Systems can provide customization services, which can include engineering, production and certification. Available are different LED reolutions and chip spacing, enclosure and mounting solutions, as well as project specific functionalities or SW interfaces to other onboard systems.
