The MITSUBISHI ELECTRIC watt-hour meter with MODBUS communication measures electrical energy in one direction and transmits readings over a MODBUS RTU network. Energy data can be collected automatically by a PLC, SCADA or energy management system rather than read manually. It is used for monitoring consumption in factories, commercial buildings and tenant submetering.
