PLC INPUT/OUTPUT MODULE

🔌 PLC Input/Output Module – The Bridge Between Field Devices and the Controller 🤖 In an industrial automation system, the PLC Input/Output (I/O) Module plays a crucial role as the interface between the real world and the control system. ✅ Input Module: It receives signals from sensors, switches, and other field devices. These signals represent the status of physical processes—like temperature, pressure, or motor position—and are sent to the PLC CPU for processing. ✅ Output Module: After processing, the PLC sends control signals to actuators, relays, motors, and lamps through the output module, executing commands that drive the machinery or process. ⚙️ Key Features: Reliable signal conversion between analog/digital devices and the PLC Electrical isolation for system protection Modular and easy to expand Supports both AC/DC inputs and outputs 💡 In short: The I/O module is the nervous system of a PLC—it senses, interprets, and acts to maintain smooth and precise control in automation. 📚 Used widely in industries like manufacturing, process control, robotics, and smart automation systems.
