Siemens 7KM2112-0BA00-2AA0 Power Monitoring Device

Siemens SENTRON PAC3200 power monitoring device, model 7KM2112-0BA00-2AA0, is a graphic LCD DIN-rail meter designed for three‑phase systems up to 690 V line‑to‑line and 400 V line‑to‑neutral, with a compact 92 × 92 mm front panel. It displays and stores essential electrical data, offering monitoring of more than 50 values and 2 GB of memory for long‑term logging and trend comparisons across the installation. The unit is powered from a universal AC/DC supply and communicates via Modbus TCP, with optional Modbus RTU, PROFINET, or PROFIBUS interfaces for integration with control systems and energy management software. The PAC3200 family provides active, reactive, and apparent energy measurements, plus voltage, current, power factor, and other network parameters captured with IEC‑compliant accuracy. Front‑panel visualization is via a monochrome graphic LCD, enabling quick status checks in electrical panels, while ring cable lug connections provide secure terminations for robust DIN‑rail installations.
