In the field of general mechanical manufacturing, it can be used as a signal relay component in CNC machine tools, injection molding machines, packaging machinery and other equipment, connecting various sensors and control hosts of the equipment, transmitting the operation status signals and control instructions of the equipment, and ensuring the precise execution of mechanical processing, molding, packaging and other processes. Auxiliary control systems in the energy and power sector that are compatible with power equipment such as thermal power and wind power, for instance, in the pitch control system of wind power equipment, analog or digital signals like wind speed and blade position can be transmitted to assist the control system in adjusting the blade Angle and ensuring power generation efficiency. It can also be used in the low-voltage control circuits of substations to achieve the collection and transmission of switch status signals. In the control circuits of equipment such as chemical reaction vessels and metallurgical blast furnaces in the fields of chemical engineering and metallurgy, temperature, pressure, flow and other detection instruments are connected to the PLC control system to transmit real-time working condition data. At the same time, control instructions are transmitted to adjust parameters such as valve opening and heating power, ensuring the stability and safety of the production process Adapt to the signal interaction requirements of high-temperature and multi-interference industrial sites in this field. In the field of automated production lines, in scenarios such as automotive assembly lines and electronic component production lines, the actuators responsible for connecting each workstation with the central controller achieve signal linkage among workstations, ensuring the orderly coordination of each link in the production line and enhancing the coordination of production rhythms and production efficiency.
