Eaton EMR-5000-2A0LB1 Motor Relay - Fiber Ethernet
Part Number: EMR-5000-2A0LB1
Quick Summary
Eaton motor relay EMR-5000-2A0LB1 protects motors in industrial drive systems, delivering reliable protection and remote monitoring for harsh environments. Engineers rely on fast fault detection and clear diagnostics to minimize downtime and prevent cascading failures. The device supports Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet for scalable, secure communication, with 16 digital inputs and 9 digital outputs to match complex motor circuits. Typical CE approvals and IP-rated options are common in motor protection relays; confirm exact certifications with Eaton for your region. By combining sensing, interlocking, and protection in a single module, it reduces panel complexity and supports faster maintenance, improving uptime and total cost of ownership.

Eaton Specification Sheet - EMR-5000-2A0LB1
Wide voltage range and protection functions. The EMR-5000-2A0LB1 accepts 19-300 Vdc and 40-250 Vac, enabling direct use with a wide range of motors and power sources. This reduces the need for external converters and simplifies stocking, leading to lower installation costs and quicker commissioning in industrial drive applications. I/O density and flexible interlocking. With 16 digital inputs and 9 digital outputs, the relay supports starter interlocks, start/stop control, and zone selective interlocking. In practice, this tightens protection coordination across motor groups, decreases nuisance trips, and shortens repair times in production lines. Networked monitoring and secure communication. Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet enables seamless SCADA integration and remote diagnostics. This reduces现场 visits, improves event logging, and supports predictive maintenance strategies. Time synchronization and I/O options. URTD Interface IRIG-B supports precise synchrony for coordinated protection schemes, important in large facilities and power distribution. The removable terminals aid installation and field service, letting technicians swap or upgrade connections without rewiring. Sensing inputs cover current, power, differential, voltage protection and metering. This comprehensive suite helps meet standards for motor protection, improves fault detection accuracy, and supports energy auditing and reporting. Practical operating metrics. Zone selective interlocking and the base EMR-4000 compatibility provide upgrade paths and easier retrofit of legacy systems.
