Product Overview
The INFI90 is a robust, modular distributed control system (DCS) developed by ABB Bailey for large-scale continuous process industrial automation. As a core component of ABB’s evolutionary Symphony automation family, this DCS platform eliminates the limitations of centralized control systems by decentralizing process monitoring and regulation across modular controllers and I/O units. It solves critical industrial pain points including unstable long-distance signal transmission, insufficient system expandability, and poor fault tolerance in heavy process industries. Featuring redundant power transfer, reliable INFI-NET bus communication, and high-precision loop control, this ABB automation system supports continuous 24/7 operation and seamless incremental system upgrades without full plant downtime. It is primarily utilized by process plant operators, system upgrade engineers, and industrial maintenance teams seeking stable, long-lifecycle DCS solutions for legacy and modernized industrial production lines.
