Programmable Logic Controller (PLC) modules are core components of industrial automation systems. They are digital computers designed for real-time control of manufacturing processes, machinery, and production lines. By processing inputs from sensors and outputs to actuators, PLC modules enable precise logic control, sequence control, and data handling. Their reliability, flexibility, and scalability make them critical in modern industries for optimizing efficiency, reducing downtime, and ensuring safe operations.
