Product Detailed Description
The Allen-Bradley (noted as a likely match for the queried based on Rockwell Automation catalog alignment) is part of the PowerMonitor 5000 series, specifically the M5 unit with native EtherNet/IP communication. It serves as a versatile base quality meter for electrical power monitoring, functioning as an ampere meter, blind power meter, frequency meter, pulse counter, voltmeter, and effective power measurement device. This compact DIN-rail mountable instrument measures key electrical parameters including real energy (kWh), reactive energy (kVARh), apparent energy (kVAh), real power (kW), reactive power (kVAR), apparent power (kVA), and demand values. It features extensive logging capabilities for time-of-use, energy, minimum/maximum values, load factor, alarms, data, events, and setpoints. The device includes a configuration lock switch to safeguard revenue-grade accuracy and supports connections via current transformers (CTs) for current sensing and potential transformers (PTs) for higher voltage applications. Its lifecycle status is active, making it suitable for ongoing industrial deployments.

Product Advantages
- Revenue-Grade Precision: Certified Class 0.2 accuracy for power, demand, and energy metering, ensuring reliable billing and compliance in critical applications.
- Seamless Integration: Native EtherNet/IP support with CIP energy objects enables easy connection to Rockwell Automation ecosystems, including FactoryTalk software, for real-time data access and control.
- Comprehensive Analytics: Advanced diagnostics like THD, K-factor, unbalance, sag/swell, and projected demand provide proactive insights to optimize energy use and prevent downtime.
- Flexible Logging and Alarms: Robust logging (e.g., TOU, min/max, events) and programmable setpoints with relay outputs allow for customized monitoring and automated responses.
- User-Friendly Configuration: Web-based interface, USB connectivity, and network sync (IEEE 1588 PTP) simplify setup and maintenance, reducing engineering time.
- Enhanced Security and Reliability: Configuration lock prevents unauthorized changes; fault indicators and duplicate IP detection ensure operational integrity.
- Compact and Versatile: DIN-rail design with multi-function metering (real/reactive/apparent) in a single unit minimizes panel space while supporting CT/PT scalability.
Precautions and Notes
- Grounding: Connect the VG terminal exclusively to the power system’s earth ground; this is a functional ground only—do not use for safety grounding.
- Installation Limits: Designed for indoor use only; avoid exposure to condensing humidity, excessive vibration (>2G), or altitudes >2000 m. Use CTs for all current inputs and PTs for voltages exceeding 690V AC to prevent damage.
- Configuration Lock: When enabled, the physical switch locks out changes that could impact revenue accuracy—document settings before activation.
- Fault Handling: Monitor status LEDs: Flashing red indicates recoverable faults (e.g., minor errors); solid red signals non-recoverable issues or CIP timeouts. Network red for duplicate IP—resolve addressing conflicts immediately.
- Certifications: Verify the product label for certifications (e.g., UL, CE, as of 2025-09-09 includes Australian RCM); older/newer units may vary.
- Load Switching: Adhere to relay ratings (e.g., inductive break: 0.55A @125V DC max) to avoid arcing or failure; test pulse outputs under load.
- Environmental: Operate within -20 to 70°C; derate for high temperatures. Ensure proper ventilation to maintain accuracy.
- Maintenance: Periodically check wiring diagnostics via the web interface; firmware updates via USB only from authorized sources to avoid security risks.
Product Applications
The 1426-M5E is ideal for industrial and commercial environments requiring precise power quality monitoring and energy management. Typical applications include:
- Energy Cost Allocation and Billing: Revenue-grade metering for sub-billing in multi-tenant facilities like data centers, hospitals, or commercial buildings.
- Load Management and Demand Response: Real-time demand projections and TOU logging to optimize peak usage in manufacturing plants or utilities.
- Power Quality Diagnostics: THD, unbalance, and sag/swell detection in sensitive processes like semiconductor fabrication or pharmaceutical production.
- Renewable Integration: Monitoring apparent/reactive power in solar/wind farms or EV charging stations for grid stability.
- Preventive Maintenance: Alarm and event logging in HVAC systems, water treatment plants, or oil/gas facilities to predict equipment failures.
- SCADA/PLC Integration: EtherNet/IP connectivity for centralized control in automated warehouses or assembly lines, enabling FactoryTalk EnergyMetrix dashboards.
