It takes a 600 V DC input and delivers a 400 V three-phase AC output at 5 A per channel (5 A/5 A), meaning it drives two independent motors from a shared DC bus in a compact booksize format. ## Key ratings and their meaning The 5 A per-channel output rating governs the motor size this module can handle — sized for small servo or spindle drives on a common DC link. The 600 V DC input is typical for SINAMICS S120 drive-line-up configurations where a line module feeds a regulated DC bus. Booksize construction with external air cooling means it slots into a multi-axis cabinet alongside other S120 booksize modules, relying on cabinet-level forced airflow rather than an integrated fan. This keeps the module depth shallow but requires the panel builder to account for airflow routing and pressure drop across the row. Optimized pulse patterns and extended Safety Integrated functions (including DRIVE-CLiQ cable) make this module suited for applications demanding low motor losses and integrated safe torque off / safe stop 1 without an external safety relay. ## Deployment context This Double Motor Module is designed for multi-axis SINAMICS S120 cabinets — packaging machines, printing presses, or material-handling lines where two axes share a common DC bus and a single control unit. The DRIVE-CLiQ interface connects back to a control unit for cyclic real-time data.","metaTitle":"Siemens 6SL3121-2TE15-0AA4 SINAMICS S120 Double Motor Module","metaDescription":"Siemens 6SL3121-2TE15-0AA4 SINAMICS S120 Double Motor Module, 600 V DC input, 400 V 3 AC output, 5 A/5 A, booksize, mature lifecycle.
