DS7-25


DS7-25 road traffic light


Function

Road traffic light is designed to regulate the movement of vehicles and pedestrians.

As a light source, light-emitting diodes mounted on a printed circuit board are used at the traffic light, which allows to reduce power consumption and provide a long service life.

The yellow component of the traffic light is combined with a time indicator designed to inform the road users about the time left before the green or red traffic lights go out. The program of the indicator is built in such a way that, when switched on, it automatically measures the traffic light time (red and green) for four cycles and for the fifth cycle it displays the remaining time of the signal lighting. During the time display, the indicator automatically monitors the traffic lights time, and if this time starts to differ from cycle to cycle by more than 0.5 seconds, the time indication automatically turns off for safety reasons.

The traffic light is manufactured in the UKhL climatic version, category 1 according to GOST R 52282-2004.
