Overview
The ABB Bailey IEMMU11 is a module mounting unit designed for use with ABB Bailey Infi 90 open distributed control systems. The module mounting unit consists of a sheet metal card chassis and a printed circuit board backplane assembly. Mounting flanges are provided for mounting the mounting unit in a standard Elsag Bailey 483-millimeter (19-inch) cabinet. This unit provides the infrastructure for secure module placement, electrical distribution, and simplified system integration in industrial automation and control applications.
Key Features
- Open top and bottom structure allow air to flow over the modules, ensuring effective passive cooling
- Modules can be installed and removed quickly and easily
- The module is held in position by card guides, the connectors on the backplane, and the module’s front panel, captive fastening latches
- Provides electrical distribution of I/O expander bus, module bus, and Controlway signals
- IEMMU11, IEMMU12, IEMMU21, and IEMMU22 are module mounting units used to house standard INFI 90 ® OPEN system modules and the BRC-100 Harmony Bridge Controller module
- Units can replace existing IEMMU01 and IEMMU02 Module Mounting Units
