The DC2SEM2L traffic light control unit can manage both traffic lights at 24V and traffic lights at 230Vac as these are driven by clean relay contacts. It has been designed for the management of 2 situations:
- 2 TRAFFIC LIGHTS WITH 2 LIGHTS in ONE SINGLE ALTERNATE SENSE , certainly the most classic and used in a narrow passage where only one car passes (garage, parking, residence etc.).
- 4 TRAFFIC LIGHTS COMBINED 2 TO TWO OPPOSED to manage a SIMPLE CROSSING , on one exit you control a road in both directions and on the other exit the road that intersects on both directions.
The traffic light control unit can operate with two operating logics, depending on the installation requirement:
Operation without detection devices (TIMED)
The alternation times of the phases in which the traffic lights are lit red or green are defined by the installer using the trimmers on board the control unit. The times of the phases are fixed, cyclical times, regardless of the volume of inbound or outbound traffic.
Operation with detection devices
The alternation times of the phases in which the traffic lights are lit red or green are defined by the installer using the trimmers on board the control unit.The difference is that it is the detection of vehicles on the corresponding entrances that activates the switch-ons of the traffic lights. This logic allows for better management of the volume of inbound and outbound traffic.
