PFXA401SF module

In the middle and late 1970s, programmable controllers entered the stage of practical development, and computer technology has been fully introduced into programmable controllers, making a leap in their functions. Its position in modern industry has been established by its higher operation speed, ultra-small size, more reliable industrial anti-interference design, analog calculation, PID function and high performance-price ratio. In the early 1980s, programmable controllers have been widely used in advanced industrial countries. The development of programmable controllers in this period is characterized by large-scale, high-speed, high-performance and product serialization. Another characteristic of this stage is that the number of countries producing programmable controllers in the world is increasing and the output is increasing. This marks that the programmable controller has entered a mature stage.

At the end of the 20th century, the development of programmable controller is more suitable for the needs of modern industry. In terms of control scale, this period saw the development of mainframes and minicomputers; In terms of control ability, a variety of special functional units have been born, which are used in various control situations such as pressure, temperature, speed, displacement, etc; In terms of the matching ability of the product, various human-machine interface units and communication units have been produced, which makes it easier to match industrial control equipment with programmable controllers. At present, the application of PLC in mechanical manufacturing, petrochemical industry, metallurgy and steel, automobile, light industry and other fields has been greatly developed.
