Q1: What is the Siemens 6SL3120-2TE21-0AA4?
It is a Double Motor Module for the SINAMICS S120 drive system in Booksize format. It controls two independent motors (2 × 9 A) from a common DC link, with Extended Safety Integrated functions and internal air cooling.
Q2: Is this product still available from Siemens?
No. It was discontinued effective 18 January 2021 (PM490 status). It is available only through remaining stock, refurbished units, or third-party suppliers.
Q3: What is the successor model?
The successor is 6SL3120-2TE21-0AD0 (C/D-type). Siemens notes that the successor requires adaptation of connectors and cables during replacement. It is functionally equivalent but not a simple drop-in without wiring changes.
Q4: What is the rated current of this module?
The rated output current (IN) is 2 × 9 A, with a base load current (IH) of 2 × 7.7 A and peak current (Imax) of 2 × 18 A per Siemens manual data. Some third-party sources list a higher peak of 2 × 27 A; verify against your specific application requirements.
Q5: What is the type power rating?
2 × 4.8 kW based on IN at DC 600 V and 4 kHz pulse frequency.
Q6: Does this module support safety functions?
Yes. It supports Extended Safety Integrated functions up to SIL 2 (IEC 61508) and PL d / Category 3 (EN ISO 13849-1).
Q7: What cooling method does it use?
Internal air cooling with an integrated fan.
Q8: What is the weight of this module?
Approximately 5.5 kg per Siemens manual data. Some third-party sources list 6.8 kg; the Siemens manual figure is authoritative.
Q9: What should I verify before ordering?
Always verify the exact part number (6SL3120-2TE21-0AA4), confirm your motor current requirement (2 × 9 A), ensure your DC link voltage matches (510–720 V), and check whether you have the necessary connectors/cables for the replacement (especially if migrating to the 0AD0 successor).
