The ABB Bailey NCOM03 is an advanced-generation Network Communication Module designed for the INFI 90 / Net 90 distributed control system (DCS). It provides high-speed, stable, and reliable communication between controllers, I/O subsystems, operator stations, and system-level network nodes.
As an evolution of earlier NCOM modules, the NCOM03 focuses on enhanced data handling efficiency, improved diagnostic capability, and stronger resistance to industrial electrical noise. It is widely deployed in power generation plants, oil refineries, petrochemical complexes, and large-scale continuous process industries, where communication reliability directly impacts process safety and operational performance.
