The Siemens 6SL3352-3AG28-5AC0 is a replacement IPD (Interface and Protection) card for the SINAMICS S150 air-cooled Motor Module basic unit, rated for 500-690V and 75kW. This is the board that handles the drive's internal logic and protection interfacing — if this card fails, the module won't communicate or run. It's classified as a spare part, not a standalone drive, so the swap is board-level: pull the old card, seat this one, and verify the firmware revision matches the rest of the drive system.
RoHS compliant since 01-07-17. Group code R2SC and product group 4Q30 are Siemens internal classification tags used for ordering and BOM filtering.
