Product Benefits

Courbes de statistiques PC Central


Compatible with all types of Central Traffic Control Stations and / or Remote Monitoring (DIASER, GERTRUDE, Criter, Siter, SURF…), TRAFFY® supports standardized or specific communication protocols via serial link RS232, GPRS/36, Ethernet TCP/IP.


Micro contrôleur


The TRAFFY controller uses very low power consumption CMS technology and integrates the constraints of sustainable development and reliability of electronic components. It has a microcontroller, a diode display on the front face and a « bus CAN » communication interface. 

Mise en fonction d'un contrôleur de carrefour


TRAFFY is a modular design intersection controller, which makes it possible to adapt its configuration, according to your needs, by the addition of racks (up to 2 more), traffic light boards and / or input / output boards.
