The Siemens 6SL3353-3AG41-0AA4 is a replacement IPD (Interface and Protection) card for the SINAMICS S120 air-cooled Active Line Module. It's the FPGA-equipped variant, rated for 500-690V three-phase AC at 50/60 Hz, handling 1025 A. This is a spare part — the board that sits between the control unit and the power stage, managing gate-drive signals, fault detection, and DC-link monitoring.
Listed as active in production — no end-of-life notice. Product class C: manufactured or produced to order, not a shelf-stocked item. Built against a confirmed order and cannot be reused or returned against credit.
The 1025 A rating at 500-690 VAC places this card in the largest frame size of the air-cooled Active Line Module family. The FPGA variant handles higher switching frequencies than the standard CPLD version.
Integration Context
This card fits inside the air-cooled Active Line Module chassis — it is not a standalone drive. The module mounts in an IP20 enclosure with forced-air cooling.
