Product Profile： A single-point signal controller, also known as a local controller, is a device that independently manages the timing of traffic signals at intersections. Additionally, it refers to a signal device that can display or modify signal timings based on instructions from a central computer within a traffic control system. The single-point signal circuit comprises several components: a panel, a motherboard, an output board (which includes JK-A motherboard and output board integration along with a fault detection board), among others. Specifically, the panel consists of a digital tube display circuit, an analog intersection display circuit, and key and indicator circuits. The motherboard incorporates an MCU, memory, watchdog, digital tube display, bus driver, RS232 and 485 interfaces, and power supply. The output board serves as the signal output driving circuit, while the fault detection board is responsible for detecting faults in the signal lamps.
