Main Features and Advantages
The Allen-Bradley 1426-M5E-DNT delivers a robust suite of metering and monitoring capabilities engineered for demanding industrial energy management applications. Its high-speed sampling architecture distinguishes it from conventional power meters, capturing 1024 data points per channel per cycle to enable precise measurement of rapidly changing electrical parameters.
High-Resolution Measurement Engine: The Allen-Bradley 1426-M5E-DNT monitors four voltage and four current channels simultaneously, acquiring 1024 data points across all eight channels every 12 to 17 milliseconds. This extraordinary sampling density allows the module to calculate over 6,000 parameters each cycle, providing comprehensive visibility into voltage, current, power, energy, demand, and power quality metrics with exceptional temporal resolution. The measurement accuracy of 0.20% meets ANSI C12.20-2010 Class 0.2 and EN 62053-22 Class 0.2 standards, ensuring reliable data for billing-grade and revenue-accurate applications.
Dual Communication Architecture: The Allen-Bradley 1426-M5E-DNT features a native EtherNet/IP port as standard, enabling seamless integration with Allen-Bradley control systems, FactoryTalk EnergyMetrix software, and plant-wide SCADA networks. The additional DeviceNet communication port provides compatibility with legacy device-level networks and supports applications where DeviceNet infrastructure is already established. This dual-communication design ensures the Allen-Bradley 1426-M5E-DNT can serve as a bridge between modern Ethernet-based energy management systems and existing DeviceNet control architectures.
Comprehensive I/O and Control Capabilities: The module includes four digital inputs for WAGES (Water, Air, Gas, Electricity, Steam) data collection, enabling pulse counting from auxiliary meters and sensors. Four digital outputs—comprising three DPDT control relays and KYZ solid-state relay outputs—support connection to SCADA systems, alarm annunciation, or direct control functions. Configurable alarms for up to 20 events allow the Allen-Bradley 1426-M5E-DNT to trigger notifications or control actions based on user-defined electrical parameter thresholds
