The 6SL3520-2XB01-1AB0 is the AB0 I/O variant of the entry-level 1.1 kW FSA G115D B-connector drive. At 3.1 A HO in the compact 380 × 156 × 129 mm FSA enclosure, it powers the lightest conveyor sections — small roller beds, labeling stations, or diverters — where the drive fits tight machine frames and expanded AB0 I/O supports a few local sensors without adding a fieldbus node.

How does this compare to the AA0 and AF0 1.1 kW variants?

AB0 provides more hardwired I/O than the basic AA0, suiting sections with multiple local sensors. AF0 integrates PROFINET and PROFIsafe for networked lines. All three share the same FSA power stage, B-connector, and IP65/IP66 protection — the choice is about how the drive connects to the control system, not about what it can drive.
