ABB M2M Meter
ABB M2M meters are intelligent network analyzers / digital power meters for industrial and commercial power distribution. Their core function is to realize remote monitoring of electrical parameters, data exchange and equipment configuration via Machine-to-Machine (M2M) コミュニケーション. They are suitable for primary and secondary power distribution in medium- and low-voltage switchboards and serve as key components in ABB’s intelligent energy management system.

- Multi-protocol compatibility: Seamless connection to industrial protocols including Modbus RTU/TCP, Profibus, Profinet, compatible with SCADA, EMS and building automation systems;
- Expandable I/O: Supports digital pulse output, programmable relay output and analog output for interlock control and alarm linkage.
- 代表的な用途
- Industrial plant power distribution: Power monitoring and energy consumption optimization for main switchboards and production line feeders, supporting equipment operation and maintenance;
- Commercial buildings / complexes: Metering for lighting, socket and air conditioning circuits in offices and shopping malls to achieve refined energy management;
- PV / エネルギー貯蔵システム: Bidirectional energy metering for accurate monitoring of power generation, grid connection and energy storage processes;
- Medium-and low-voltage distribution O&M: Remote monitoring of switchboard status to reduce on-site inspection costs and improve operational efficiency.
- Key Selection Guidelines
- Match communication requirements:
Small projects / remote meter reading: Choose M2M Basic (basic Modbus RTU);
Industrial sites / multi-device networking: Choose M2M MODBUS (dual-protocol compatible);
High-speed remote access / cloud platform connection: Choose M2M ETHERNET (built-in Web server + Modbus TCP);
- Adapt to installation scenarios: For 96×96mm panel mounting, select the general-purpose model; for rail mounting, use the DIN rail compatible version;
- Function priority: For power quality analysis, select models with THD measurement; for bidirectional metering, confirm 4-quadrant function support first;
- Replacement and upgrade: Discontinued models can be replaced by the M1M series digital multifunction meters, with M2M functions realized by adding communication modules.
