The 6SL3520-2XB01-5AA0 is the simplest configuration at the top of the FSA power range: 1.5 kW in a 380 × 156 × 129 mm IP65/IP66 B-connector enclosure, with basic AA0 I/O Control. At 4.1 A HO, it runs small belt transfers and roller beds where minimal hardwired signals (run/stop, e-stop) suffice and a fieldbus is not required.

When is this the right 1.5 kW FSA variant?

Choose AA0 for a standalone conveyor section with one or two sensors — a short belt between two workstations, or a packaging outfeed with a single position switch. The compact FSA footprint fits tight machine frames, the fanless design runs silent, and the basic I/O keeps wiring and cost to a minimum. For multi-sensor sections, AB0 provides more I/O; for PROFINET lines, AF0 integrates safety over the network.
