摘要：
PLC is a kind of special order to the industrial control microcomputer system. In order to adapt to the requirement of sequence control, Out the microcomputer some Numbers of PLC function, and strengthen the function of logic control, Is a kind of between relay control and computer control automatic control device; PLC is designed for use in harsh industrial environments, so has a strong anti-interference ability. In addition to the input/output part adopts photoelectric isolation measures, the power supply, arithmetic unit, controller, storage and so on also set up many kinds of protection and shielding. PLC is not relay the mechanical contact, therefore, there is no contact of poor contact, fusion welding, wear and damage of coil, etc.
