Siemens 6SL3055-0AA00-3AA1 SINAMICS S120 Terminal Module TM31 Digital/Analog I/O Drive Module

The Siemens 6SL3055-0AA00-3AA1 is a SINAMICS Terminal Module TM31, an add-on board for the SINAMICS S120 modular drive system with digital and analog inputs and outputs for I/O expansion. It carries an IP20 enclosure for cap (DIN) rail mounting, weighs 0.49 kg, and is manufactured in Germany under HS code 8504.90.90.

Technical Specifications

Selection Notes

Because the module carries digital and analog I/O rather than motor power, it is selected when a SINAMICS S120 line-up needs extra hardwired signal points — interlocks, analog setpoints, temperature sensor inputs — beyond what the Control Unit or a Motor Module already provides, rather than as a substitute for either. IP20 and cap-rail mounting mean it belongs inside a control cabinet, not in an open panel or field location.

Applications

Provides additional digital and analog inputs and outputs for a SINAMICS S120 drive configuration where the Control Unit's onboard I/O is insufficient, mounted on a DIN/cap rail alongside other SINAMICS S120 modules in the control cabinet.
