The ABB Bailey NMMU01 Network 90 Module Mounting Unit is a structural rack and chassis component designed for the ABB Bailey INFI 90 / Net 90 Distributed Control System (DCS). It provides the physical mounting framework for Network 90 modules, ensuring stable installation, precise alignment, and secure electrical connectivity within industrial control cabinets.
Unlike functional processing modules, the NMMU01 serves as the backbone of system architecture—supporting module organization, simplifying maintenance, and enabling scalable expansion of Bailey control systems. In large industrial environments, this mounting unit is essential for keeping complex DCS configurations organized, accessible, and operationally stable.
Its rugged industrial design ensures long-term reliability in demanding environments such as power generation and petrochemical facilities.
