Eaton Specification Sheet - EMR-4000-2A1HB0
IEC 61850 over Ethernet RJ-45 enables standard-based interconnectivity across drives and automation networks. With Modbus/DNP3 TCP over the same interface, it supports enterprise-wide monitoring and control, reducing integration effort and commissioning time. I/O flexibility includes eight digital inputs, five digital outputs, and four analog outputs, enabling complex motor control sequences while simplifying wiring and reducing hardware count. Zone selective interlocking and IRIG-B URTD interface provide time synchronization and selective fault clearance, enhancing safety and diagnostics in high-availability lines. Conformal-coated circuit boards deliver reliability in dusty, humid, or temperature-variant environments, extending uptime and reducing maintenance windows. A standards-aligned Ethernet interface and clear documentation support rapid deployment and easier upgrades across plant networks.

FAQs
Plan for the device’s footprint of 8.06 in length, 8.7 in height, and 9.72 in width, with a weight of about 9.259 lb. Use eight digital inputs, five digital outputs, and four analog outputs to minimize external controllers. Connect via the Ethernet RJ-45 for IEC 61850 and Modbus/DNP3 TCP, and ensure enclosure protection suitable for the environment. Verify wiring integrity and confirm approvals with the manufacturer for your region.
The device supports phase currents of 5A and 1A, with eight digital inputs, five digital outputs, four analog outputs, and zero analog inputs. Input supply ranges include 19–300 VDC and 40–250 VAC to suit diverse motor types. I/O options include IRIG-B URTD, and Sensitive Ground Input, enabling precise control and timing for motor protection and metering tasks.
Yes. EMR-4000-2A1HB0 features IEC 61850 over Ethernet RJ-45, plus Modbus/DNP3 TCP over Ethernet, enabling standard-based interoperability with substation and industrial drive networks. This makes it well-suited for integrated protection, metering, and remote monitoring across factory floors and energy-management systems.
Compliances are documented with the manufacturer. While Eaton products commonly align with regional CE and related safety standards, confirm the specific approvals for your site with Eaton or your distributor to ensure compliance for your operating region and application.
Key ROI drivers include the device’s conformal-coated circuitry for rugged environments, time synchronization via IRIG-B for accurate diagnostics, and zone selective interlocking to reduce fault energy. Its Ethernet-based communications simplify integration and remote monitoring, while the 8/5/4 I/O configuration supports complex control with fewer external controllers. The warranty and readily available documentation also shorten maintenance cycles.
