Eaton EMR-5000-2B1LB0 motor relay - Motor protection relay
Part Number: EMR-5000-2B1LB0
Quick Summary
The Eaton EMR-5000-2B1LB0 motor relay is designed to deliver reliable motor protection and remote diagnostics in industrial automation environments. Engineers often struggle to integrate protection relays without undermining uptime or data visibility across control networks. This device bundles two analog inputs, eight digital inputs, and nine outputs with Mbus TCP or DNP3 TCP/UDP over LC fiber, supporting 50/60 Hz operation and voltage ranges from 19-300 VDC and 40-250 VAC. Compliance details are specified by the manufacturer and should be confirmed for each market. In practice, that means faster fault isolation, better asset management, and reduced maintenance costs through configurable protection logic and scalable monitoring.

FAQs
Begin by confirming compatibility with the EMR-4000 base relay and ensure the panel has removable terminals for fast wiring. Configure the IO mapping (2 analog, 8 digital inputs, 9 digital outputs) and set the 50/60 Hz operation. Use Mbus TCP or DNP3 TCP/UDP over LC duplex fiber for remote communication and integrate with your SCADA or PowerPort-E tool during commissioning. Verify proper grounding and bus timing to prevent spurious trips and ensure zone selective interlocking is correctly aligned with neighboring relays.
Key specs include 50/60 Hz operation, voltage range of 19-300 VDC and 40-250 VAC, phase current options of 5A and 1A, and IO consisting of 2 analog inputs, 2 analog outputs, 8 digital inputs, and 9 digital outputs. Communications support Mbus TCP and DNP3 TCP/UDP over LC duplex fiber. The device uses removable terminals and supports semi-flush mounting for flexible installation in panel enclosures.
The EMR-5000-2B1LB0 is well suited for motor protection in manufacturing lines, large drive systems, and conveyor networks where reliable protection, data visibility, and remote diagnostics are critical. Its 2/8/9 IO configuration and differential, voltage, current protection enable precise fault detection. Zone selective interlocking and IRIG-B time synchronization make it ideal for complex multi-motor installations in power, process, and packaging industries.
Specifications call for manufacturer-complied certifications, and local market requirements should be confirmed with Eaton. While the data sheet notes manufacturer compliance, engineers should verify CE marking, IP protection levels, SIL ratings, or other regulatory standards as applicable in their region and industry. Always cross-check with the Eaton specification sheet before deployment in regulated environments.
By consolidating analog and digital IO with robust remote communication, this relay reduces wiring complexity and enables centralized monitoring, which shortens diagnostic cycles and minimizes downtime. The device’s protection features—differential, voltage, current metering—improve fault detection accuracy, lowering maintenance costs and extending motor life. ROI is driven by uptime gains, faster commissioning, and scalable integration with SCADA systems.
