Solution for complex junctions with demanding requirements

Key Features

  • for systems with up to 96 signal-groups
  • two 32-bit CPU for multichannel-monitoring
  • up to 48 inputs | 24 outputs
  • for 40 VAC-LED signal heads
  • lamp voltage 40 and 230 V
  • lamps can be freely assigned


The deTRA3000II traffic light controller is designed for complex junctions. Due to its modular design and the extremely low wiring requirements the system can be flexibly adapted to the respective application. The controls are arranged in a centralized structure but can be expanded to a decentralized layout. By default, the control unit is designed for twelve switch cards and for systems with up to 48 signal groups but it is also possible to expand to 96 signal groups.


  • control modes: automatic schedule systems, central or manual control, traffic dependent control, coordination, fixed time program
  • public transport prioritization using radio/R09.X-telegrams
  • LISA+ direct supply
  • easy to assemble 19” technology
  • time coordination via GPS
  • modern TFT touch display for operation
  • integrated web server for remote access


Due to its modular design the processing unit of the deTRA3000II can be used both in stationary and portable systems. The selection if switch cards depends in the on-site conditions.

Switch Cards

The SK LED2 40V and SK LED2 230V switch cards are used in a centralized structure by default for controlling the deTRA300 device. Depending on different requirements dresden elektronik provides a suitable switch-card for every purpose. Please take a look at our swich card overview.
