ABB

ABB automation hardware covers distributed control, PLC, I/O, communication, power and interface functions used in process and machine-control systems. Its architecture is commonly modular, combining controllers or processors with local and remote I/O, communication interfaces, terminal units, power modules and application-specific boards. Depending on the platform, products may use backplane, fieldbus, Ethernet or dedicated system links to exchange process data and control commands. This collection groups ABB components used for analog and digital signal acquisition, logic execution, network communication, equipment interfacing and system expansion. It includes hardware from several ABB control generations, helping maintenance teams identify replacement modules by part number, functional role and system family while keeping legacy installations serviceable.
