The 6SL3520-2XB05-5AA0 is the AA0 I/O Control variant of the 5.5 kW FSC G115D B-connector drive — the essential-configuration option for conveyor sections where the drive needs only basic hardwired signals: start/stop, direction, and a single safety input. At 13.2 A HO with 200% 3 s overload, the FSC power stage handles the same load range as every other 5.5 kW G115D variant.

When is AA0 I/O Control the right choice over AB0 or AF0?

Choose AA0 when your conveyor section has minimal local sensor count and no fieldbus requirement. A simple belt section with one position switch and an e-stop loop wired to the drive's digital inputs is the AA0 sweet spot — the hardware is simpler, the wiring is lighter, and there is no unused I/O capacity. If the section carries multiple sensors (jam detection, speed feedback, temperature) that must terminate at the drive, the AB0 variant provides additional I/O without adding a fieldbus. For PROFINET-integrated safety, step up to AF0.
