The ABB M1M 12 Modbus is a digital multifunction electrical power meter designed to monitor electrical parameters and track active energy consumption in single-phase and three-phase installations. It measures electrical quantities using current transformer (CT) inputs rated at 1 A or 5 A and supports communication through the Modbus RTU protocol via an RS-485 interface. This allows measured data to be integrated into building management systems, SCADA platforms and industrial energy-monitoring systems. The meter is designed for front-panel installation, has a nominal 96 × 96 mm face size, and provides active-energy measurement accuracy of ±1%.
