The 6SL3520-1XD00-3AB0 is the Standard I/O variant at the entry-level 0.37 kW power step in the 1XD D-connector SINAMICS G115D family — 1.3 A HO (2.6 A LO) in the FSA compact frame (380 × 156 × 129 mm, ~4.7 kg) with natural convection cooling. AB0 provides terminal-based control with a different I/O configuration than AA0 — suitable for applications that need hardwired control signals but with the Standard I/O pinout and signal set. Operates at 380–480 V three-phase, compatible with IE2/IE3/IE4 motors across 0–550 Hz, IP65 sealed.

1XD00-3: three communication variants at the smallest G115D

The 0.37 kW FSA power step now supports all three G115D communication interfaces in the 1XD D-connector family: AA0 (I/O Control) for basic terminal signals, AF0 (PROFINET with PROFIsafe) for networked safety-integrated control, and AB0 (Standard I/O) for terminal control with an alternate I/O configuration. All three share the identical 1.3 A HO FSA hardware — the communication suffix is the sole differentiator. The complete comm set means no compromise between power sizing and control architecture at the smallest G115D rating.
