Collection: ABB Bailey Infi 90 / Net 90

ABB Bailey Infi 90 / Net 90 is an industrial control-system family used for continuous process control, plant automation, and installed-base lifecycle support. Its architecture typically combines controllers or processor modules, distributed I/O, communication interfaces, termination hardware, power components, and system buses. Technical characteristics vary by module and may include bus protocol, channel configuration, redundancy, isolation, signal type, rack position, and compatible controller generation. The collection covers processing, signal interface, network, field connection, and supporting system functions within the platform. Functionally, these components support process data acquisition, control execution, device communication, alarm handling, and data exchange between field equipment and supervisory layers. Correct replacement requires matching the exact model, hardware revision, electrical specification, communication architecture, and system generation used in the installed control system.
