The deTRA300 traffic light controller is designed for small junctions and pedestrian
 crossings. It is characterized by absolute reliability and performance. Due to its extremely compact design, it is easily assembled and ready for use in the control cabinet. By default, the compact low-cost device is designed for two switch cards and for systems with up to eight signal groups.


  • extendable via CAN Bus
  • time synchronization via DCF signal
  • Control modes: automatic schedule system, manual control, traffic-dependent control, coordination, fixed time program
  • possible extensions: LISA+, VS-Plus, traffic computer connection (OCIT –O V1.x/V2), public transport prioritization
  • also suitable for mobile usage

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 switch-card overview.
