RTU (Remote Terminal Unit) is a critical component in industrial automation and control systems, designed to monitor and manage field devices remotely. These rugged, reliable units gather data from sensors and equipment, transmitting it to central control systems for real-time analysis and decision-making. Key features of RTUs include advanced communication protocols (Modbus, DNP3, IEC 60870), robust environmental tolerance (wide temperature ranges, shock/vibration resistance), and modular I/O configurations for flexibility. Typical RTU products in this category encompass: compact RTUs for small-scale deployments, high-density RTUs with extensive I/O capacity, wireless RTUs for remote locations, and RTUs with integrated PLC functionality. These devices are essential for SCADA systems, oil/gas pipelines, water treatment plants, and power distribution networks, enabling efficient automation with features like edge computing, cybersecurity protections, and redundant power supplies.
