Schneider Electric M907-000 Memory Module PCB is a 16K memory module designed for Modicon 900-series PLCs (originating in the AEG Modicon line), packaged as a plug-in PCB that mounts to the controller backplane to provide dedicated memory for the processor’s program and data. Cataloged as PCB-M907-000 or M907-000 in Modicon/AEG listings, some sources note the REV A revision of this module. It fits legacy Modicon systems where additional RAM is required to support larger ladder logic, data storage, and state retention within the 900-series controller ecosystem.
