programmable logic controller circuit diagram time to understand the problems that existed before programmable controllers. Chapter 2 Before the Programmable Controller Before the days of the PLC the only way to control machinery was through the use of relays. Relays work by utilizing a coil that, when energized, creates a magnetic force to effectively pull a switch to the ON or OFF position.
PLC is just a term that has stuck for many kinds of modular, rail-mount, easily programmable controllers with specific IO needs. PLCs were the next step from relay control blocks.

Key learnings: PLC Definition: A programmable logic controller is a specialized computer designed to operate in industrial settings, managing and automating the mechanical processes of factories and plants.; Functionality: PLCs handle tasks like timing and logic operations, significantly streamlining industrial processes.; Programming Flexibility: The programming of a PLC can be altered to A PLC's primary function is to control the functions of a system utilizing the underlying logic that it has been programmed. PLC s (Programmable Logic Controllers) is common in industry today. Proper PLC system design can give many years of service to a machine or process while also increasing efficiency & profitability for the company that PLC Inputs and Outputs (I/O) PLC Ladder Logic; Programmable Logic Controllers (PLCs) are small industrial computers with modular components designed to automate customized control processes. PLCs are often used in factories and industrial plants to control motors, pumps, lights, fans, circuit breakers and other machinery.
