The ABB IMAMM03 is an analog master module for the INFI 90 Rack I/O platform. It coordinates analog I/O processing and communication within a legacy Bailey rack I/O station.
The ABB IMAMM03 is documented with analog master function, i/o expander bus architecture, works with compatible analog slave modules. These characteristics define the signal, network, or control role that must be matched during replacement.
ABB IMAMM03 must be selected from its complete identity and the receiving-system evidence. Coordinates the analog master side of the legacy rack i/o arrangement.
ABB identifies IMAMM03 as an Analog Master Module in its official spare-parts literature. Apply only to the complete IMAMM03 identity.
Before connection, match the matching analog slave population, I/O expander bus, rack power and configured function blocks.
Document the installed state, then validate slave communication, loop values and configured channel handling.
