Series Description
The ABB Bailey INFI 90 Series represents a landmark in the evolution of industrial automation, particularly in the field of distributed control systems (DCS). Originally developed by Bailey Controls and later acquired by ABB, the INFI 90 Series has long served as a reliable backbone for controlling and monitoring complex industrial processes. Its sustained use across sectors such as power generation, chemical processing, and manufacturing highlights its enduring relevance, even as newer technologies emerge.
System Overview and Technical Specifications
The INFI 90 Series features a distributed architecture, which spreads control functions across multiple modules and processors. This design ensures high reliability and redundancy, essential for continuous operation in industrial environments where downtime can result in substantial financial losses.
Its modular structure allows for extensive customization, with components such as I/O modules, communication modules, and control processors tailored to specific operational requirements. Key modules—including INIC101, INNIS01, and INICT01—play vital roles in data exchange, interface management, and overall system integration.
