Features:
- Four channels accept KTY84-130, Pt1000, or PTC temperature sensors.
- Protective separation is rated up to 480 V AC on the sensor side.
- Two DRIVE-CLiQ interfaces place the TM120 in the SINAMICS signal path.
6SL3055-0AA00-3KA0 organizes four temperature measurements in one cabinet-mounted terminal module.
Its sensor circuits use a defined 2 mA current and preserve an electrically separated boundary from the converter side.
Firmware scope matters when Pt1000 elements are selected because support starts with V4.7 HF17.
The Siemens 6SL3055-0AA00-3KA0 TM120 Terminal Module is listed as Active / Available from OEM.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Temperature input organization
- Channel layout: Four inputs keep the connected temperature sensors on defined individual circuits.
- Sensor selection: KTY84-130, PTC, and Pt1000 elements use the same TM120 input stage.
- Firmware boundary: Pt1000 evaluation is enabled from firmware V4.7 HF17.
- Measurement current: Each channel supplies 2 mA to its connected sensor.
Separated sensor boundary
- Electrical separation: Sensor circuits are isolated from the converter-side electronics.
- Voltage limit: The protective separation rating extends to 480 V AC.
- Channel purpose: Temperature signals enter through the separated sensor section before DRIVE-CLiQ transfer.
- Earth connection: An M4 protective-earth point establishes the module chassis reference.
Drive-system connection
- Interface count: Two DRIVE-CLiQ ports support insertion into the SINAMICS topology.
- Module role: The TM120 adds external temperature-sensor channels to the converter system.
- Cable scope: The ordering configuration does not include a DRIVE-CLiQ cable.
- Supply path: A separate 24 V DC feed powers the terminal module electronics.
Conductor and protection checks
- Sensor conductors: The permitted cross-section spans 0.2...6 mm² (AWG 24...10).
- Line-side conductor: The supply connection is specified for 2.5 mm² (AWG 14).
- Supply loading: The 24 V DC input draws 0.50 A under the rated configuration.
- Protection ceiling: Upstream fuse protection must not exceed 20 A.
