GE 1426-M5E-DNT Power Monitor Module | DNP3/TCP Ethernet Connectivity Unit

Technical Specifications

Main Features and Advantages

Robust Industrial Ethernet and DNP3 Connectivity: The primary function of the GE Multilin 1426-M5E-DNT​ is to provide robust, standards-based network communication. Its 10/100 Mbps Ethernet port offers high-speed data throughput, enabling efficient polling of the extensive data points available in a Power Monitor 5000 without network congestion. The implementation of the DNP3 protocol is a significant advantage for utilities and industrial facilities, as it is a mature, widely adopted, and interoperable standard designed for reliability in critical monitoring and control applications. DNP3 supports unsolicited reporting, allowing the 1426-M5E-DNT​ module to immediately notify the master station of alarm conditions or changes of state, ensuring timely operator awareness of power system events.Secure and Flexible Data Integration: The module supports DNP3 Secure Authentication, providing a layer of security to prevent unauthorized control or configuration commands, which is crucial for protecting critical infrastructure. As a DNP3 outstation, it can map the Power Monitor 5000’s vast array of measurements—including volts, amps, kW, kVAR, kVA, kWh, power factor, frequency, and harmonic distortion—into standard DNP3 data objects (analog inputs, binary inputs, counters). This structured data model simplifies integration with any SCADA or control system that supports DNP3, such as GE’s iFIX, Siemens WinCC, Ignition, or other major platforms. The GE 1426-M5E-DNT​ effectively future-proofs the power monitoring investment by enabling seamless data flow to modern IT/OT systems for advanced analytics, dashboarding, and enterprise energy management.Simplified Configuration and Management: The module is designed for ease of integration. It is configured using industry-standard tools like the GE EnerVista suite, which provides intuitive windows for setting IP addresses, DNP3 polling parameters, data point mapping, and security settings. This streamlined configuration process reduces engineering time and minimizes the risk of setup errors. Once operational, the GE Multilin 1426-M5E-DNT​ provides reliable, “set-and-forget” communication, requiring minimal ongoing maintenance. Its design as a plug-in module also offers flexibility; if network requirements change, the module can potentially be upgraded or replaced without affecting the core measurement capabilities of the Power Monitor 5000 unit itself. This modularity protects the initial hardware investment and adapts to evolving communication needs.

Application Field

The GE Multilin 1426-M5E-DNT​ module is deployed wherever a GE Multilin Power Monitor 5000 device is used for critical electrical system monitoring and requires integration into a centralized SCADA or energy management system via Ethernet. In electric utility substations (transmission and distribution), the Power Monitor 5000, equipped with the 1426-M5E-DNT, serves as a sophisticated feeder or transformer monitor. It streams real-time power quality data, demand information, and event logs via DNP3 to the utility’s control center, enabling operators to maintain grid stability, manage load, and quickly locate faults.Within large industrial and commercial facilities, this module is key to comprehensive energy and power management. Facilities like manufacturing plants, data centers, hospitals, and universities use Power Monitor 5000 devices at main incoming service entrances, critical feeders, and large load centers. The GE 1426-M5E-DNT​ module allows all these distributed monitors to communicate over the site’s Ethernet network to a central SCADA or Power Monitoring System (PMS). This provides facility managers with a unified, real-time view of energy consumption, power quality disturbances, and demand peaks across the entire campus, enabling cost allocation, identifying energy waste, preventing equipment damage from poor power quality, and ensuring compliance with utility tariffs. In water and wastewater treatment plants, the module facilitates the integration of power monitoring for large pumps and aeration systems into the plant’s overall process control system, creating a unified operational view. Essentially, the GE Multilin 1426-M5E-DNT​ is the essential communications enabler for transforming local electrical measurements into actionable, enterprise-wide intelligence.
