Advantages and disadvantages of PLC control and relay control

1, strong function and high cost performance (it can be equivalent to integrating many relays, and the cost performance is not low most of the time. It may not be practical unless it is a simple circuit with only a few relays. )

2. Complete hardware, humanization and strong adaptability.

3, high reliability and strong anti-interference ability

4. The workload of system design, installation and debugging is less.

5, the programming method is simple

6. Less maintenance workload and convenient maintenance.

7. Small size and low energy consumption

8. Keep pace with the times and realize network communication.

There is only one disadvantage: it cannot be used as a circuit breaker in the main circuit and can only be controlled by logic.

If you don't understand anything, you can ask.

I hope my answer can help you.
