DC2SEM2L - Traffic light control unit 2 traffic lights with 2 lights
& Nbsp;

Control unit traffic light to manage 2 traffic lights with 2 lights - 24 V and 230 V.
Cyclical time operation or with vehicle detectors.
& Nbsp;

The control unit universal electronics DC2SEM2L has been designed for the management of 2 traffic lights with 2 lights, in situations where driveway access regulation is necessary alternately (garages, parking lots, residences etc.).

The control unit can operate with two operating logics, depending on the installation:
Operation without vehicle detection devices
& Nbsp;

The times of alternation of red / green-green / red and red / red semaphore phases come defined by the installer and are fixed, cyclical, regardless of the volume of the incoming or outgoing traffic and the incoming or outgoing transit order. In this case we will speak of "cyclic operation".

Operation with vehicle detection devices

The alternation times of the red / green-green / red semaphore phases red / red are defined by the installer, but to activate the ignitions is the detection of vehicles on the corresponding entrances (entry and exit) through the special devices installed (photocells, radar, etc.). This logic allows better management of the volume of incoming and outgoing traffic and the order of entry and exit.
