The S15 – SC is an updated version of one of the most emblematic models of SEMAVENCA, the S15 controller, whose performance, robustness and adaptability have earned it the preference of costumers nationwide for over 8 years, with hundreds of units sold and installed throughout the national territory.

Among the improvements included for this version are the increase of processing speed, data storage capacity, and the integration  of a GPS module that allows the auto – synchronization of consecutive road intersections without the need for communication between controllers.

The equipment is built in a modular way. The layout and configuration of the output switches radically changes allowing the size and weight of the equipment to be reduced, additionally the structure wiring is eliminated providing a cleaner finish and eliminating any possibility of welding or cable rupture failures.

It meets with the requirements of the COVENIN 2753 – 1999 standard and most of the NEMA TS2.
