Siemens 6SN1118-0DG21-0AA1 Simodrive LT Module

Siemens 6SN1118-0DG21-0AA1 Simodrive LT Module is a Servo Add-On Module/Board designed for use with Siemens SIMODRIVE control systems. The unit is described as an LT Modul INT. 15A, indicating an internal current rating of 15 amperes for compatible SIMODRIVE configurations. Identified by the part number 6SN1118-0DG21-0AA1, this module is documented within Siemens and aftermarket catalogs as a SIMODRIVE LT component that complements the main drive, enabling integration with existing servo drive setups such as the SIMODRIVE 611-D family. In typical automation and machine-control applications, it serves as an auxiliary expansion to support precise servo performance within a broader SIMODRIVE installation, helping to manage current delivery and control signals in coordinated motion systems.
