The 6SL3520-1XC04-0AB0 is the Standard I/O variant of the 1XC04 C-connector SINAMICS G115D at 4 kW for SIMATIC control systems — 10.2 A HO (20.4 A LO) in the FSB fan-cooled enclosure (425 × 180 × 169 mm, 7.52 kg) with an integrated cooling fan. AB0 provides terminal-based Standard I/O control, joining AF0 (PROFINET) as the second confirmed communication variant at 1XC04. Operates at 380–480 V three-phase, compatible with IE2/IE3/IE4 motors across 0–550 Hz, IP65 sealed.

Why choose AB0 Standard I/O for a 4 kW SIMATIC drive?

AB0 Standard I/O suits applications where the 4 kW drive is controlled by a SIMATIC PLC via hardwired digital/analog signals rather than PROFINET — for example, when the PLC's PROFINET ports are fully allocated or when the drive is a retrofit into an existing terminal-based control panel. The C-connector provides the power and I/O interface in a single compact connector, preserving the machine-mount form factor. If the application can use PROFINET, the AF0 variant (1XC04-0AF0) adds remote diagnostics, PROFIsafe, and multi-drive coordination — all over the same Ethernet cable.

1XC04 variants at a glance

Both share the same 4 kW FSB fan-cooled hardware, same C-connector, same 10.2 A HO — the communication suffix determines the control interface. AA0 (I/O Control) is structurally expected but not yet observed at 1XC04.
