Siemens 7KM2112-0BA00-3AA0 Power Meter Module

Siemens 7KM2112-0BA00-3AA0 is a SENTRON PAC3200 power monitoring device designed for three-phase electrical systems, featuring a built-in LCD display for local readings, direct connection for up to 5 A, and voltage ratings of L-L: 690 V and L-N: 400 V, enabling direct measurement in common industrial panels. It can measure and display apparent, active, and reactive energy, with accuracy classes of 0.5 acc. to IEC61557-12 or 0.5s acc. to IEC62053-22, and is powered by a wide-range power supply unit AC/DC with screw-terminal connections for reliable, compact installation. Communications are provided by Modbus TCP by default, with optional Modbus RTU, PROFINET, or PROFIBUS interfaces to integrate with PLCs, building management systems, and other automation equipment. This model is part of the PAC3200 family and has been superseded by Siemens 7KM3220-0BA01-1DA0.
