Bailey NMMU02 Module Mounting Unit

Bailey NMMU02 Module Mounting Unit is a Bailey/ABB Infi-90 backplane accessory designed to host modular control cards within a Symphony chassis. This module mounting unit serves as the foundational interface between the Infi-90 rack backplane and individual modules, enabling orderly installation and removal of Bailey intelligent modules and related cards in industrial automation environments that rely on the Elsag Bailey Infi-90 family. In typical installations, the NMMU02 sits in the module mounting area of the rack to organize and support the expansion or peripheral modules that populate the backplane, helping maintain a clean, serviceable control cabinet. The device is identified by the model number NMMU02 and is cataloged as a Module Mounting Unit used with Bailey/Infi-90 systems, including the Symphony rack architecture, where it forms part of the modular system’s physical infrastructure for mounting multiple cards. This mounting unit is commonly employed in process-control applications that depend on Bailey’s modular approach to device integration, providing a dedicated mechanical interface that accommodates the system’s module lineup and backplane connections.
