The 6SL3520-1XH65-5AA0 is the hardwired-I/O variant of the G115D 5.5 kW FSC distributed drive under the 1XH65 sub-code. At 26.4 A output with an integrated cooling fan in the FSC frame, it delivers mid-to-heavy conveyor power with the simplest control interface in the G115D lineup — four digital inputs and an analog speed reference input.

1XH65 — what the sub-code means

The 1XH65 is one of several G115D sub-codes at the 5.5 kW power level. Like the 1XH25 (also 5.5 kW FSC), it uses the FSC frame with an integrated fan drawing approximately 540 mA from the 24 V DC rail. The sub-code difference typically reflects hardware revision levels or regional product variants within Siemens' manufacturing system — the electrical specification, frame dimensions (425 × 240 × 169 mm), and functional capability are shared across same-power G115D sub-codes. For the installer and end user, the mounting pattern, wiring terminals, and commissioning workflow are identical.

Hardwired I/O for 5.5 kW conveyor sections

At 5.5 kW, the drive powers accumulation conveyors, inclined belt sections, and roller conveyors handling moderate-to-heavy product weights. The AA0 hardwired interface keeps control simple: run/stop on digital inputs, speed reference on 0–10 V or 4–20 mA. For brownfield conveyor systems where the control architecture predates industrial Ethernet and multi-core signal cables already run alongside the motor leads, this variant integrates without pulling new network cable or adding switch ports. The integrated C2 EMC filter handles conducted emissions without external components.
