Quick Summary

Eaton EMR-5000-2B1CA0 motor relay is a versatile protection device that guards motors and enables remote monitoring across 50/60 Hz drives. Engineers often contend with costly downtime and misconfiguration when deploying protection schemes; this model reduces risk with differential protection, a robust 2 analog input and 2 analog output interface, plus 8 digital inputs and 9 digital outputs for flexible control. Compliances should be confirmed with the manufacturer, and Eaton’s policy provides a structured warranty (one year from installation or eighteen months from shipment, whichever occurs first). With Modbus TCP or DNP3 TCP/UDP over Ethernet RJ-45, this relay integrates smoothly into modern plant networks while supporting 19-300 VDC and 40-250 VAC motor circuits for broad compatibility.

FAQs

Yes. The EMR-5000-2B1CA0 is designed for integration with typical motor control architectures, featuring Ethernet RJ-45 for Modbus TCP or DNP3 TCP/UDP. It supports 50/60 Hz systems and common supply ranges (19-300 VDC, 40-250 VAC). Removable terminals aid field wiring, while its zone selective interlocking supports safe, coordinated tripping in MCC environments.
The relay includes 2 analog inputs, 2 analog outputs, 8 digital inputs, and 9 digital outputs for flexible control and monitoring. It provides differential protection, voltage/current protection, metering, and 50/60 Hz operation. This combination improves fault detection, reduces nuisance trips, and supports precise trip coordination in motors and pumps used in conveyors and processing lines.
It's well-suited for industrial drives in manufacturing, packaging, and material handling where robust motor protection and remote diagnostics are valuable. With Modbus TCP/DNP3 TCP/UDP, it integrates into SCADA and energy-management systems, and its differential protection helps coordinate protection schemes for high-inertia motors and pumps across 50/60 Hz networks.
Compliances are labeled as 'Contact Manufacturer' for this model; confirm with Eaton for CE markings, SIL considerations, IP enclosure ratings, and any industry-specific approvals required for your installation. The device includes a standard warranty (one year from installation or eighteen months from shipment), which supports post-installation assurance and service planning.
By enabling remote diagnostics via Ethernet and offering precise protection, the relay reduces field troubleshooting time and enables faster fault isolation. The combination of local I/O flexibility, remote communication, and reliable protection curves translates to lower downtime, predictable maintenance scheduling, and improved total cost of ownership for motor-driven equipment in continuous-process environments.
