PLC, also known as programmable logic controller, is the abbreviation of the English name Programmable logic Controller. Mainly used in industrial control, automation and intelligent manufacturing control systems.

In PSA nitrogen production systems, it is very common to use PLC. It can be used to control the opening and closing of the pneumatic valve in PSA nitrogen generator, so that the two towers work alternately; with the assistance of the corresponding control algorithm, a constant gas supply can be achieved; production efficiency can be improved and all work can be carried out safely.

In addition to greatly improving the safety and stability of the entire PSA nitrogen production system, PLC's precise pneumatic valve control also effectively controls the energy consumption of the equipment and reduces unnecessary consumption of electricity.

At the same time, another shining point of PLC is that it can realize fully automatic on-site nitrogen production without any supervision. The participation of PLC makes the PSA air separation nitrogen production system more economical, safe and efficient in production.

Advantages of PLC

1. Reliable and strong anti-interference ability

2. Simple programming and strong versatility

3. Small size, compact structure and light weight

4. Easy to install and maintain, easy to modify, and low energy consumption

In recent years, PLC, like the PSA nitrogen production system, has been developing forward. As a general industrial control device with computer functions, I believe that it will have broader application value in the near future.
