Integrated circuits are made using semiconductor manufacturing techniques, where many transistors, resistors, capacitors, and other components are fabricated on a small single crystal silicon chip, and the components are assembled into a complete electronic circuit using multi-layer or tunnel wiring methods. It is represented by the letter “IC” (also known as the literal symbol “N”, etc.) in the circuit.
1. High reliability and strong anti-interference ability
High reliability is a key performance of electrical control equipment. PLC adopts modern large-scale integrated circuits.

It is represented by the letter “IC” (also known as the literal symbol “N”, etc.) in the circuit.
The technology is manufactured using strict production processes, and the internal circuits adopt advanced anti-interference technology, which has high reliability. Using PLC to form a control system and equivalent scale relay contactors.
Contactors are a widely used switching appliance. Contactors are mainly used for frequent connection or disconnection of AC and DC main circuits and large capacity control circuits. They can be operated remotely and can be used in conjunction with relays to achieve timed operation, interlocking control, various quantitative control, and voltage loss and undervoltage protection. They are widely used in automatic control circuits, and their main control object is electric motors. They can also be used to control other power loads, such as electric heaters, lighting, welding machines, capacitor banks, etc.
Compared to the system, the electrical wiring and switch contacts have been reduced to hundreds or even thousands of times, greatly reducing faults. In addition, the PLC has a hardware fault self detection function, which can send out alarm messages in a timely manner when a fault occurs. In the application software, the application can also program fault self-diagnosis programs for peripheral devices, enabling circuits and equipment in the system other than PLC to also receive fault self-diagnosis protection. In this way, the reliability of the entire system is extremely high.
2. Complete supporting facilities, complete functions, and strong applicability
Today, PLC has developed into a series of products of various scales, which can be used in various industrial control occasions. In addition to logical processing functions, most PLCs have comprehensive data processing capabilities and can be used in various digital control fields. A variety of functional units have emerged in large numbers, allowing PLC to penetrate various industrial controls such as position control, temperature control, CNC, etc. With the enhancement of PLC communication capabilities and the development of human-machine interface technology, it has become very easy to use PLC to form various control systems.
3. Easy to learn and use, highly welcomed by engineering and technical personnel
PLC is an industrial control equipment for industrial and mining enterprises. It has an easy interface and programming language that is easily accepted by engineering and technical personnel. The graphical symbols and expressions of ladder diagram language are quite similar to relay circuit diagrams, opening the door for those who are not familiar with electronic circuits, computer principles, and assembly language to engage in industrial control.
