Product Overview

The 1426‑M8E is high‑end PowerMonitor 5000 M8 power quality meter for industrial energy and power‑quality monitoring. It captures voltage and current waveforms, calculates more than 6000 electrical parameters each cycle, delivering revenue‑accurate energy metering plus advanced power‑quality analytics including harmonics up to 127th order, interharmonics, flicker, transient detection, sag‑swell event classification and waveform recordingRockwell A…. Built‑in web‑server allows browser‑based configuration and data reading without dedicated software. EtherNet/IP interface enables seamless integration with Rockwell ControlLogix PLC, FactoryTalk and SCADA systems for energy accounting, equipment load profiling and power‑quality troubleshooting. Virtual wiring correction function resolves wiring errors via software setting without hardware rewiring. Rugged hardware design tolerates industrial vibration and wide temperature fluctuation, ideal for heavy‑EMI factory‑floor, power‑plant and petrochemical control‑room environments.
