ABB IEMMU11 Module Mounting Unit chassis for INFI 90 OPEN Symphony systems

ABB IEMMU11 rear-mount chassis for INFI 90 OPEN Symphony systems

The ABB IEMMU11 is a rear-mounted module mounting unit designed to house and interconnect up to twelve ABB INFI 90 OPEN control and I/O modules within Symphony Enterprise Management and Control System cabinets. It serves as the structural and electrical backbone of the system.

Integrated backplane with primary power distribution

• Supports installation of up to 12 standard INFI 90 modules
• Distributes primary AC or DC power to compatible power modules
• Routes regulated system voltages across the chassis backplane
• Provides internal Controlway, Module Bus, and I/O Expander Bus paths

Rear-access chassis architecture

The rear-mount design allows installation and maintenance from the back of the control cabinet, making it suitable for enclosed industrial panels where rear service access is required.

Industrial control system applications
