Technical specification for traffic light controller
1. General Provisions
1.1. Assign the Scientific and Production Individual Enterprise “Jahan Elektronik” to manufacture traffic light controllers model TSK-02 (TSK-04) for use with modern LED traffic lights that meet the technical requirements of 2025.
1.2. The use of TSK-02 and TSK-04 controllers should contribute to improving road traffic safety, optimizing operational costs, enhancing conditions for road users, and improving the ecological situation in cities.
2. Technical Specifications
2.1. Operating temperature range: -20°C to +65°C.
2.2. Operating voltage range: 170 V to 260 V.
2.3. Functional Capabilities:
2.3.1. Number of output circuits: 20.
2.3.2. Rated load current per output circuit: 4.0 A (8 electrical lamps of 100 W each).
2.3.3. Total load current switchable at any given time: up to 25 A.
2.3.4. Number of control programs: at least five.
2.3.5. Control phases:
TSK-02 controllers: 2 or 3 phases.
TSK-04 controllers: 4 phases.
2.3.6. Maximum duration of control cycle: up to 150 s; main direction: up to 75 s.
2.3.7. Smooth switching of lamps using a “zero” pulse.
2.3.8. “Night economy” mode, in which lamps operate at 50% power.
2.3.9. Monitoring of burned-out filaments of red signal lamps with automatic switching of the traffic lights to flashing yellow signals if all red signals in one direction are absent.
2.3.10. Traffic lights start sequence: “yellow flashing,” followed by “all red.”
2.4. Prospective Capabilities:
2.4.1. Time adjustment via cellular communication for decentralized coordination control.
2.4.2. Connection of remote display clocks with real-time accuracy of 1 second.
2.4.3. Transmission of traffic light controller status to the control center (power outage, burnout of all red lamps in one direction, normal operation, real-time value accurate to 1 second).
2.4.4. Setting “green wave” or “green for convoy” modes via cellular communication.
3. Delivery Set
3.1. Standard Delivery:
3.1.1. Microprocessor unit.

3.1.5. Battery.
3.1.6. Additional control block for green outputs by voltage.
3.1.7. Control panel (one per 10 units).
3.1.8. Electrical cabinet (for 1 controller), designed for climate conditions and potential expansion of controller functions.
3.1.9. Technical documentation (one set per 10 controllers).
3.2. Optional Additional Equipment:
3.2.1. Cellular communication module.
3.2.2. Data exchange module.
4. Safety Requirements
4.1. Monitoring of “green” outputs by current, voltage, and insulation parameters to prevent simultaneous activation of conflicting signals.
4.2. Automatic switching of traffic lights to flashing yellow signals if all red lamps in one direction are burned out.
5. Additional Conditions
5.1. Ensure automatic switching of control programs.
5.2. Availability of control panels for setting controller parameters.
5.3. Possibility of integration with existing traffic management systems.
5.4. Provision of warranty support and service maintenance throughout the entire service life.
