TRAFFIC CONTROLLER S-4F

EQUIPMENT DESCRIPTION

The S4F is low cost, small size traffic controller, specially designed for low – complexity intersections where it `s not necessary to manage the flow of more than 4 phases. It complies with the COVENIN 2753 – 1999 STANDARD requirements.

GENERAL CHARACTERISTICS

  • 4 programmable phases as vehicular or pedestrian.
  • Setting the order of the phases output sequence.
  • A detector per phase, configurable as vehicular, pedestrian or as omission of the pedestrian or vehicular phase.
  • Intermintent output fully configurable per phase, allowing the yellow or red lights to be placed intermittently.
  • 16 configurable work plans, each of 8 intervals.
  • 9 work cycles including programmed flashing cycle 0.
  • Test rutine to diagnose functioning of control.
  • 16 characters x 2 line backlit LCD display for use in dimply lighted enviroments.
  • 4 modes of operation: normal mode, semi – acted, police panel, synchronized mode with GPS.
  • Real time clock with lithium battery backup with a duration of 9 years.
  • Storage in non – volatile memory with an information backup for a period of more than 40 years.
  • Temperature sensor for air extractor control (optional).
  • Solid state output switches integrated into a single card with zero cross load activation.
  • Ability of activate load of both incandescent and high brightness LED lamps.
  • Synchronization via GPS module.
