Siemens LCD Power monitoring device control panel instrument Part number 7KM3220-1BA01-1EA0

Product Overview

The Siemens 7KM3220-1BA01-1EA0 is a SENTRON PAC3220 power-monitoring device, designed for installation in control panels and switchboards. With a 96 mm × 96 mm front panel and graphical LCD display, it measures and monitors key electrical parameters such as voltage, current, power, energy, frequency and more — making it ideal for energy management, sub-metering, and power-system monitoring in industrial, commercial or large residential installations.

Key Features

• Full digital power monitoring device (SENTRON PAC3220 series)
• Graphical LCD display (96 mm x 96 mm) for clear visualisation of electrical parameters
• True RMS measurement of voltage and current — accurate even with distorted waveforms
• Measures voltage, current, active/reactive/apparent power, energy (import/export), frequency, power factor, and more
• Supports modular current input (1 A or 5 A) with external current transformers for flexible installation
• Digital inputs (2) and outputs (2) for alarm/pulse or control functions
• Integrated communication interface (Ethernet) supporting Modbus TCP for remote monitoring and data integration
• Front panel protection class IP65 (suitable for panel mounting in control rooms)

Applications

The 7KM3220-1BA01-1EA0 is ideal for energy monitoring, sub-metering and power-management applications in industrial plants, commercial buildings, data centres, and large residential complexes. It can replace analog meters, provide detailed consumption and demand data for energy management, support load-analysis, and integrate into building-management or automation systems via Modbus TCP. Additionally it is suitable for monitoring backup power systems, UPS installations, motor control centres, and any electrical distribution where real-time and historical data on power and energy usage is required.
