FAQs
Plan for projection mounting and ensure a compatible control network when integrating with Eaton automation platforms. Use the fiber optic Ethernet paths to connect IEC 61850 and Modbus/DNP3 TCP communications, and account for the URTD interface options including IRIG-B timing for synchronized operations. Verify wiring conventions, grounding practices, and enclosure protection to maximize reliability in harsh environments.
The EMR-3000-2A1KB1 supports 5 A and 1 A phase currents with four digital inputs, four digital outputs, and one analog output. It operates from 19–300 Vdc or 40–250 Vac at 50/60 Hz, enabling flexible power sourcing for mixed environments. This combination delivers responsive motor control, accurate fault signaling, and scalable I/O for automated lines without excessive external hardware.
Yes. The unit lists IEC 61850 and Modbus/DNP3 TCP communication over LC duplex fiber optic Ethernet, which supports modern substation and process automation networks. This integration reduces EMI, improves reliability, and simplifies remote diagnostics and control in demanding electrical infrastructure applications.
Certification details are not listed in the provided data. Please contact Eaton to confirm CE, SIL, IP ratings, and other regulatory certifications. The product does indicate compatibility with IEC 61850 and Modbus TCP over fiber, which aligns with common industrial standards and enables compliant integration in many control environments.
With conformal-coated boards and a robust fiber optic interface, maintenance intervals can be extended due to improved environmental resilience and reduced EMI. The warranty offers one year from installation or eighteen months from shipment. ROI emerges from reduced wiring, fewer external modules, easier diagnostics, and faster deployment across motor-driven applications such as conveyors and pumps.
