FAQs

Begin by selecting a suitable enclosure with space for the 9.72 x 8.7 x 8.06 inch footprint. Mount the unit and connect URTD, IRIG-B wires, and fiber optic cables per the Eaton specification sheet. Power the device with 19–300 VDC or 40–250 VAC as required, then configure digital I/O (8 DI, 5 DO) and analog outputs (4 AO) to your control system. Verify network addressing and time synchronization to ensure accurate metering and protection actions.
Plan for phase current ratings of 5A and 1A sensing, 8 digital inputs, 5 digital outputs, and 4 analog outputs. The unit also provides current, voltage, and power protection and metering with versatile I/O options. This combination supports complex motor control schemes, fault isolation, and rich process signaling while keeping wiring complexity manageable.
Yes. The EMR-4000-2A0KA1 supports IEC 61850 over LC duplex fiber optic Ethernet as well as Modbus and DNP3 TCP over the same fiber network, enabling seamless integration with modern substations and automation networks. This interoperability reduces integration time and improves data visibility for operators and engineers.
The product lists 'Compliances: Contact Manufacturer,' so verify CE, SIL, IP ratings, and other regulatory certifications with Eaton for your application. For mission-critical or hazardous environments, obtain formal confirmation to ensure regulatory alignment and safety approvals before field deployment.
ROI comes from reduced downtime due to integrated protection and metering, fewer field components, and centralized data for energy optimization. The unit’s versatile IO and fiber-enabled communications streamline maintenance, shorten troubleshooting cycles, and support predictive maintenance by delivering accurate motor health and energy data over standard industrial networks.
