ABB IEMMU01 is a standard 19-inch rack featuring 12 universal slots that support the mixed installation of various INFI90 process control cards (such as AI/AO/DI/DO, controllers, and communication cards). It incorporates an internal system bus to facilitate data exchange and module-to-module communication. Working in conjunction with INFI90 power modules, it supplies regulated +5 VDC, ±15 VDC, and +24 VDC power to all installed cards. Field wiring connects to the rear of the rack, making it well-suited for the layout of large control cabinets in power plants, chemical facilities, and similar industrial environments.
