What is the difference between relay logic and PLCs?

Understanding the Difference Between Relay Logic and PLCs

When it comes to industrial automation, understanding the difference between relay logic and PLCs is crucial. Relay logic refers to the use of traditional electromechanical relays to control processes in a sequential manner. On the other hand, Programmable Logic Controllers (PLCs) are electronic devices that are specifically designed for automation and can perform complex functions with ease.

Key Differences:

• Relay logic operates using physical switches and relays, while PLCs use a microprocessor-based system for control.
• PLCs offer more flexibility and scalability compared to relay logic systems.
• Relay logic is prone to wear and tear, while PLCs are more reliable and require less maintenance.
