PLC programmable controller is the traditional Chinese medicine field of terminal block application. The development of controller is the vane of terminal block, so the development of PLC affects the heartstrings of terminal connector.

PLC is a device that uses programmable memory to store instructions, perform logic, sequence, timing, counting and calculation functions, and control various mechanical or production processes through analog or digital input/output components. At present, PLC adopts modern large-scale integrated circuit technology, which has the advantages of small size, low energy consumption, strong anti-interference ability, etc., and plays a vital role in the field of industrial automation.

Industry development status

In recent years, PLC has been actively applied in lithium battery, metallurgy, electric power, textile machinery, logistics equipment and other industries in China, with great market potential. Data shows that the scale of China's PLC market in 2020 will be 13 billion yuan. At present, European and American brands and Japanese brands occupy a dominant position in China's PLC market, and there is broad room for domestic brands to replace them. Due to the complex process of large and medium-sized PLC and the high requirements of users for product safety and anti-interference, foreign brands occupy a monopoly market position with their leading technical advantages and perfect sales and service networks. Small PLC is mainly used for low-end OEM users. In recent years, domestic brands have achieved significant increase in industry penetration in the small PLC market by virtue of their cost-effective, flexible business model and customized model development capabilities in specific industries.

Industry development trend

The product scale of bipolar development. On the one hand, the scale of PLC products will develop to small and super small PLC with faster speed and higher cost performance ratio to meet the needs of stand-alone and small automatic control; On the other hand, it is developing towards large PLC with high speed, large capacity and perfect technology; The development trend of communication network. PLC network control is the current trend of control system and PLC technology development. The network communication between PLC and PLC, and between PLC and the host computer has been widely used; And drive integration. With the increasingly high requirements of PLC on product technology and solutions for software capability, a single dimension of general-purpose products will be difficult to meet the market demand in the future, and integrated dedicated aircraft will become the future development trend; Modular and intelligent development of products. In order to meet the needs of various control systems in industrial automation, PLC manufacturers have developed many new devices and modules in recent years, such as intelligent I/O modules, temperature control modules and special intelligent modules for detecting PLC external faults.

In the face of the significant increase in the penetration rate of domestic PLC in the industry, it is the pursuit of every connector person to cater to the industry development trend, provide PLC with appropriate terminal connectors, and improve the hard strength of China's PLC industry.
