The Siemens 6SL3351-3AH32-6DA0 is a SINAMICS G130 replacement IPD card — a board-level spare for the drive's internal interface and processing logic. It carries Group Code R2SC and Product Group 4Q30, which are the Siemens internal classification tags for this assembly line. The product class C designation means it is manufactured or produced to order and cannot be reused or returned — so order exactly what the BOM calls for, because this one stays on the drive once fitted.
What the Class C Means for Your Order
Because this is a product class C item, it is made to order and not stocked on a shelf for immediate pick. The packaging quantity is one piece, and the quantity unit is also one piece — you order one card, you get one card. That makes it a board-level swap for a G130 drive that has lost its IPD card; you are not buying a subassembly or a kit. If you are planning a panel build, factor in the made-to-order lead time rather than expecting same-day ship.
