SINAMICS S120 Double Motor Module input: 600 V DC output: 400 V 3 AC, 18 A/18 A type of construction: booksize internal air cooling optimized pulse patterns and support of the extended Safety Integrated functions incl. DRIVE-CLiQ cable
Q: What does the Siemens 6SL3120-2TE21-8AA3 do?
A: It supplies and regulates electrical power for Siemens servo or drive systems.
Q: Is this a logic controller?
A: No. It handles power delivery, not control logic.
Q: Why are these modules often kept as spares?
A: Because failure results in immediate downtime and they can have long OEM lead times.
Q: Can this be tested before installation?
A: Yes, power modules are often bench-tested to verify proper operation.
The 6SL3120-2TE21-8AA3 is a Double Motor Module from Siemens' SINAMICS S120 series. This module is designed for use with DC 600V input and has an output of 3AC 400V with 18A per phase. The frame size is booksize and features internal air cooling for optimal performance.
The 6SL3120-2TE21-8AA3 boasts numerous notable features that make it a top choice for various applications. Its optimized pulse sample allows for precise motor movement control, making it ideal for applications where smooth and accurate motor control is required. This is particularly useful in industries such as robotics or automation, where precise motor control is essential. In addition to its optimized pulse sample, the 6SL3120-2TE21-8AA3 also supports the extended safety integrated functions of the SINAMICS S120 series. These functions include safety shutdowns, emergency stop, and other measures to ensure the safe operation of the motor module. This is important for applications where safety is a top priority, such as manufacturing. Another standout feature of the 6SL3120-2TE21-8AA3 is its inclusion of a Drive-CLIQ cable. This cable allows for easy communication and data exchange with other devices in the SINAMICS system, simplifying integration into larger systems. This is particularly useful for applications where the motor module is just one part of a larger system, such as in a factory setting.
The 6SL3120-2TE21-8AA3 has dimensions of 14.0" x 4.0" x 22.0" and a weight of 15 lbs. Its tariff code is 8504907500 and it is made in Germany.
This Double Motor Module is compatible with Siemens' SINAMICS and SINAMICS S120 systems. It can be easily integrated into these systems thanks to its support of the extended safety integrated functions and the inclusion of the Drive-CLIQ cable.
