Industrial NMFC04 Multi-Function Controller Module PLC

The Bailey NMFC04 Multi-Function Controller Module (PLC) is the central processing unit of ABB's Bailey Network 90 / Infi 90 automation family. As a multi-function controller, it provides flexible analog, digital, and slave I/O support, serving as the core controller module for coordinating complex control strategies across a distributed network. Designed for Network 90 / INFI 90 environments, the NMFC04 integrates with other modules and field I/O to handle process and discrete control tasks and data exchange within a robust DCS architecture. The related IMMFC04 documentation notes that Bailey-equivalent controllers support four communication channels on the module bus, with connectivity provided by a dedicated Bailey Controls interface. The NMFC04 is used in legacy Bailey Net 90 / Infi 90 installations and in systems that require tight integration with Bailey I/O networks and control logic.
