![]() ![]() However, the amount of relays, wires and space needed to create even simple automation was problematic. ![]() In the early to mid 1900s, automation was usually done using complicated electromechanical relay circuits. Industrial automation began long before PLCs. To understand the purpose of PLCs better, let’s look at a brief history of PLCs. PLCs are often used in factories and industrial plants to control motors, pumps, lights, fans, circuit breakers and other machinery. Programmable Logic Controllers (PLCs) are small industrial computers with modular components designed to automate customized control processes. ![]() So, without further delay, let’s jump right into our introduction to PLCs!īeginner’s Free PLC Training Series Outline If you have any questions about this content, please feel free to comment on the post.
