An automation control system is the technology that enables a process or machine to operate automatically with minimal human intervention. At its core, the system uses a central "brain," such as a PLC or microcontroller, to interpret data from sensors that monitor real-world conditions like temperature, position, or flow. Based on this information, the controller sends precise commands to actuators—such as motors, valves, and heaters—to perform physical tasks. The ultimate goal is to enhance productivity, improve safety, and increase precision far beyond what is manually possible.
