The Siemens 6SL3355-2DX00-1AA0 is an SBA Safe Brake Adapter rated for 230 V AC and 2 A, designed for safe brake control within SINAMICS drive systems. It handles the switching and monitoring of holding brakes on motor shafts, ensuring the brake releases and engages safely during operation.
The 230 V AC / 2 A rating governs the brake coil it can drive. A 2 A continuous rating covers most standard holding brakes on servo and main-spindle motors up to the SINAMICS S120 modular drive range. The adapter integrates into the DC-link and control interface of the drive, so the brake supply is coordinated with the motor holding torque profile. As a Safe Brake Adapter, it supports the safe brake control function (SBC) per EN 61800-5-2, which means the brake is tested for correct opening before the motor is enabled. If the brake fails to open, the drive stays inhibited — a standard requirement for vertical-axis loads where a dropped load is a safety risk.
For BOM planning, the active status and mature stage indicate stable supply with no imminent obsolescence risk.
