A distributed I/O system allows remote I/O modules (analog/digital inputs/outputs, counters, communication ports, etc.) to be spread across a plant or facility, connected through industrial communication protocols (Modbus, Ethernet/IP, PROFINET, etc.). These systems reduce wiring complexity, increase flexibility, and improve control system scalability. Advantech is a leading global provider of industrial automation and IoT solutions. Its remote I/O modules and industrial controllers are known for ruggedness, reliability, and integration with SCADA, PLCs, and cloud platforms. 📂 Main Categories of Advantech I/O and Controllers 🔌 1.
