The wireless traffic light controller system is RF wireless operated, fully automatic, timing based and programmable. The system is custom designed for multi-road junctions and different traffic sequences. We design and manufacture traffic light controller system and sequencer for a wide variety roadways and railways applications. The complete system consists of a programmable master controller unit (control and operate) and multiple slave units (to control the traffic lights). The slave units have multiple (potential-free) relay outputs points. There can be 1/2/3/4/5 or even upto 8 slave units controlled from the same master unit.
The master control unit can be programmed to control a variety of different light on / off sequences for various directions of traffic. These sequences contain individual timing of Red->Amber->Green, Flash light timing etc. The individual timing parameters can be programmed as per requirement or traffic load conditions.
This traffic light controller system is also capable of operating in manual mode, with a dedicated sequence button for each of type of traffic conditioning. Any time during the operation of automatic mode, the user can press the manual button to enter manual mode. In manual mode, the traffic lights can be controlled as per button press. Example, press 1 to make direction 1 Green and other directions are Red. Similarly, press 2 to make direction 2 Green and so on. Pressing the mode button, brings the system back to automatic mode. The master controller has an interactive menu system (operated via the menu buttons and LCD screen), to program different timing parameters of the system.
A master controller is mandatory at a particular junction. It can control more than 1 slave controllers by sending radio commands. Receiving the commands the slave controller switches the lights in a particular sequence. All timing parameters can be programmed for operating the lights. The timing values operate at an accuracy of +/- 0.5seconds. Other than road traffic operation, flasher timing values can also be programmed.
The sequences and flasher timing can be fed in the master controller. The slave unit's relay can drive AC or DC loads of traffic lights. The limit of load capacity of the relays: 7A/250VAC or 10A/125VAC or 12A/120VAC or 10A/28VDC. Any LED light / normal light loading less that the specified limits can be applied on the output ports to control.
