Product Description: Siemens 6SN1123-1AA00-0EA2

The Siemens 6SN1123-1AA00-0EA2 is a CU310-2 PN control unit from the SINAMICS S120 series, engineered for standard drive and motion control tasks. It features an integrated PROFINET interface for seamless real-time communication with PLCs and higher-level controllers. The CU310-2 PN uses the DRIVE-CLiQ protocol to link with power modules, enabling rapid parameterization, diagnostics, and firmware updates via TIA Portal or STARTER software. Housed in an IP20 DIN-rail enclosure, it delivers reliable performance in industrial environments.
