A Programmable Logic Controller (PLC) is a ruggedized computer designed for real-time control of industrial machines and processes. PLCs are widely used in manufacturing, energy, and transportation industries to automate repetitive tasks and improve operational efficiency.
PLCs operate by receiving input signals from sensors and executing pre-programmed logic to control outputs such as motors, valves, and actuators. They are essential for process automation, enabling high-speed data processing, precise control, and system reliability.
Modern PLCs integrate with SCADA, DCS, and IoT systems, allowing for remote monitoring and predictive maintenance. Their flexibility and scalability make them a foundational component of industrial automation.
