The PowerLogic ION8600 meter is available in three different models:

ION8600C: power and energy metering, event and min/max logging, 32-channel historical logging, dip/swell monitoring, harmonics (to 31st) and symmetrical component measurement, setpoints, digital and analogue I/O, and Internet-enabled multi-port communications.
ION8600B: adds expanded 320-channel historical logging, harmonics to 63rd, Modbus master capability.
ION8600A: adds expanded 800-channel historical logging, harmonics to 127th, waveform capture, fast transient detection, and power quality compliance monitoring.

Characteristics (some features are optional):

ANSI socket or switchboard mount, customisable LCD display
3-phase, 4-quadrant metering, class 0.2 accuracy (IEC, ANSI)
Voltage, current, power, frequency, power factor, demand, energy, and time-of-use metering
