The Siemens 6SL3520-0XE00-3AA0 is the most affordable entry point to the SINAMICS G115D distributed drive platform — 0.37 kW (0.50 hp, 1.3 A) in the FSA frame with standard AA0 PROFINET/EtherNet/IP fieldbus. It delivers the full G115D feature set (IP65/IP66, C2 EMC filter, STO SIL2) at the lowest cost in the range, making it the default choice for small single-zone conveyor drives where every euro of BOM cost matters.
