Performed functions

  • Galvanic decoupler to control (test) of power circuits from a power line;
  • protection of output power circuits against a short circuit with automatic traffic lights shutdown;
  • monitoring of lamps blowing (breakage);
  • detection of “red” and “green” lights conflict with automatic traffic lights shutdown;
  • monitoring of power circuits locking between each other.
Features & Benefits

  • Quantity of the controlled traffic phases is up to 32;
  • quantity of traffic directions is up to 60;
  • the quantity of serviceable sensors and detectors has been increased up to 64;
  • reading of the controller settings data from an external flash drive;
  • recording of the controller settings data to an external flash drive;
  • saving of a crossroad certificate in PDF format;
  • adjustable switch of programs by taking into account holidays (including religious holidays);
  • centreless coordination including the mode: master-slave;
  • availability of a built-in engineering module;
  • flexible distribution and setup of the increased number of power channels (up to 128);
  • low minimum controlled electric current in each power channel is up to 10mА allowing connection and control of LED charging (up to 3 W);
  • generation of info signals at an alarm pedestrian panel (wait, go and etc.);
  • the possibility to apply as follows as transport detectors: induction, coil (loop), infrared, radar, video and wireless detectors;
  • possibility to synchronize the watch upon GPS signals;
  • possibility to connect and control a road controller by using wire (Start, Ethernet) and wireless channels of the automated traffic control system (GSM).
