Product Description: Siemens 6SN1123-1AA00-0EA0

The Siemens 6SN1123-1AA00-0EA0 is a DIN-rail mounted control unit from the SINAMICS S120 modular drive family. As the CU310-2 DP variant, it provides essential control functionality with a built-in PROFIBUS DP interface for communication with PLCs and higher-level automation systems. Designed for standard motion tasks, it supports cyclic and acyclic data exchange, basic diagnostics, and parameter management via the DRIVE-CLiQ network. The CU310-2 DP pairs with power modules (PM) to form a complete drive axis in applications such as conveyors, pumps, and fans.
