It takes a 600 V DC bus input and delivers two independent 400 V 3 AC outputs, each rated at 9 A, packaged in the booksize format with internal air cooling. This module supports optimized pulse patterns and the extended Safety Integrated functions, including the necessary DRIVE-CLiQ cable for communication back to the Control Unit. The lifecycle stage for this order code is listed as mature, meaning it is not in active new-production ramp but remains supported for ongoing applications. The datasheet carries a revision date of 07.01.2021, which is the document version, not a production end date. For a mature spare part like this, availability runs through independent distribution channels. ## Integration notes for a booksize double motor module The booksize form factor mounts in a standard SINAMICS S120 cabinet lineup alongside other booksize modules and the line-side power supply. Internal air cooling means it relies on the cabinet's forced-air flow path — verify clearance above and below the module for the cooling channel. Each of the two 9 A outputs drives a separate motor, typically a servo or induction spindle on a multi-axis machine. The DRIVE-CLiQ interface daisy-chains to the Control Unit and other modules; the cable is included per the spare part designation.","metaTitle":"Siemens 6SL3120-2TE21-0AA4 SINAMICS S120 Double Motor Module","metaDescription":"Siemens 6SL3120-2TE21-0AA4 SINAMICS S120 Double Motor Module, 600 V DC input, 400 V 3 AC output, 9 A/9 A, booksize.
