An electronic controller is usually used, if the wiring effort is too high for certain functions/systems, logic connections are required, or system processes need to be simplified. Most technical devices and systems in all economic sectors require electronic controllers.
Electronic control systems use electronic components to regulate other devices or systems, often relying on a loop that compares input and output signals to achieve a desired outcome. They can be found in digital controllers for sensors, power electronic controllers for various applications, and temperature controllers for specific needs. Additionally, programmable logic controllers (PLCs) and electronic control units (ECUs) are used in industrial automation and vehicles, respectively.
