The E61C20 Panel Mount Power and Energy Meter provides basic four
quadrant metering capability with Modbus communication via Ethernet
cable. It includes voltage and current inputs with digital and optical
outputs with a multi-tariff feature for storing accumulated energy data.
The E61C20 requires external power to operate.
