⚙️ What are Digital Inputs and Outputs (DIO)? Binary control for automation and industrial testing
DIOs (Digital Inputs/Outputs) are essential interfaces in automation and testing systems, allowing the reading and control of digital signals — that is, binary signals with only two possible states: on/off (1/0). They are used to interact with sensors, actuators, relays, valves, and other industrial devices. DIO boards or modules are
