What it is and where it fits
The Siemens 6AG1123-2DB03-2AX0 is an industrial automation module with PROFINET and Ethernet onboard, plus MODBUS TCP/IP for integration with Modicon or third-party SCADA. It supports DCP for IP assignment without a separate tool, and covers a -20 to 60 °C operating range for unconditioned enclosures. Rear protection is IP20, requiring a clean, dry environment behind the panel gland plate.
