ABB Bailey IMMFC04 Multi-Function Controller Module for Infi 90 / Net 90 is a one-slot, single-width control module designed for use in the Infi 90 open-module environment. It installs in the Module Mounting Unit and communicates on the Infi 90 network to coordinate tasks between other controllers and I/O modules within the distributed control system. The IMMFC04 is powered from a +5 V DC supply and typically draws about 8 VA, reflecting its compact, low-power design. As part of the Infi 90 family, this module functions as a central controller piece that supports integration with additional Infi 90 components to form scalable automation configurations for process and manufacturing applications. Its compact form factor and networked operation enable flexible sequencing and control roles across modules, contributing to a maintainable, modular automation architecture typical of Bailey/Infi 90 installations. This device embodies ABB’s Bailey lineage in distributed control systems, offering compatibility within the Infi 90 / Net 90 ecosystem and enabling straightforward expansion by adding compatible modules as automation needs grow.
