Siemens AG 6SL3055-0AA00-3AA1 Terminal Module

Siemens 6SL3055-0AA00-3AA1 Terminal Module is the TM31 add-on board for SINAMICS drives, delivering digital and analog in- and output capabilities in an IP20 enclosure for cap rail (DIN rail) mounting. Version A, Working Unit denotes a ready-to-use TM31 module configured as a terminal expansion that attaches to a SINAMICS drive to extend local I/O, simplifying wiring inside the control cabinet. This module provides a compact interface for external devices—digital inputs for sensors and start/stop signals, digital outputs for actuators, and analog I/O for sensor feedback or control signals—without needing a separate cabinet-mounted I/O module. The part number 6SL3055-0AA00-3AA1 identifies the specific TM31 add-on board designed for SINAMICS systems, enabling seamless integration with Siemens automation hardware. Typical installation involves clipping the TM31 onto a standard DIN rail inside the drive cabinet, connecting to the drive’s control terminals through standardized connectors, and sharing 24 V or other supply rails as required by the external circuitry. Overall, the TM31 Terminal Module extends SINAMICS capability by providing readily accessible I/O near the drive, reducing external wiring, and supporting streamlined commissioning in industrial automation setups.
