FAQs
EMR-5000-2A0KB1 is designed to be compatible with the EMR-4000 base relay, allowing a seamless upgrade path without a full system redesign. Begin by verifying the base relay footprint and wiring schematic, then migrate the protective logic and I/O mapping to the new module. Use the removable terminals to simplify field wiring and ensure clean connections during the upgrade.
Key specifications include a wide input voltage range of 19-300 Vdc and 40-250 Vac, a 50/60 Hz frequency rating, 16 digital inputs, 9 digital outputs, and current rating options of 5A and 1A. The device supports power, current, voltage, and differential protection sensing, enabling robust motor protection and metering within industrial drives.
Yes. The EMR-5000-2A0KB1 includes IEC 61850 over LC duplex fiber optic Ethernet and Modbus/DNP3 TCP communications, enabling interoperable, high-speed data exchange for protection schemes and remote monitoring. This makes it well-suited for modern substation-like protection in large motor populations and plant-wide networks.
Compliances are specified by the manufacturer and should be confirmed in Eaton's official documentation for your region. The warranty is one year from the date of installation or eighteen months from shipment, whichever occurs first. This warranty coverage supports lifecycle maintenance and protects against early field failures.
ROI hinges on reduced downtime, faster fault isolation, and simplified commissioning due to fiber-based Ethernet communications. With 16 DI and 9 DO I/O, wide voltage support, and base-relay compatibility, maintenance costs drop as wiring complexity decreases and future upgrades become modular, enabling scalable protection for growing motor networks.
