The Siemens 7KM3133-0BA00-3AA0 is a measuring device module designed for electrical energy monitoring applications. This model, part of the SENTRON PAC3100 series, provides accurate measurement of both active and reactive energy across three phases, making it suitable for systems operating between 277 and 480 volts at 50 or 60 Hz. It features a clear LCD display and communicates via Modbus RTU, allowing for straightforward integration into automation and energy management systems. The unit includes a wide-range power supply that supports both AC and DC inputs and uses screw terminal connections for secure wiring. While this specific model has been succeeded by the Siemens 7KM3120-0BA01-1DA0, it remains a reliable option for energy measurement needs. This device is available through BSP Automation, offering convenient access for industrial automation projects.
