Smart Traffic Lights

Model No. DL 2121 

This system represents a  crossing between two one-way streets,  each controlled by a semaphore and provided with three pedestrian crossings with semaphores, too.

The automatic control of the semaphore system is  performed  through  PLC  not  with  the  normal  cyclic  timing:
only the presence of at least one car determines the green signal of the relevant semaphore, allowing the transit of all the cars between the two detecting sensors.
The dialogue between the semaphores of the two roads allows the alternation of the green signal as a function of the traffic intensity, while the pedestrian crossing is on request.
The present cars are displayed through LED, whose control is assigned to an electronic circuit separated from the PLC.
Complete with educational manual and software.
Power supply: single-phase from mains.

NOTE: It can be connected to a PLC such as the DL 2210A or the DL 2210B.
