Eaton EMR-5000-2B1CA1 Motor Relay - 50/60 Hz
Part Number: EMR-5000-2B1CA1
Quick Summary
The Eaton motor relay EMR-5000-2B1CA1 is a robust motor protection device for industrial drives and motor control in manufacturing environments. Engineers often struggle with integrating protection logic, diagnostics, and remote monitoring across distributed motor assets. Certification details are listed by the manufacturer; please verify CE, IP, or SIL status with Eaton. Designed for scalable control networks, the EMR-5000-2B1CA1 combines Modbus TCP or DNP3 TCP/UDP over Ethernet RJ45 with flexible I/O and a compact mounting footprint, delivering reliable protection while enabling fleet-wide visibility and proactive maintenance. This translates to higher equipment availability, easier compliance reporting, and a lower total cost of ownership for plant-wide motor protection strategies.

FAQs
The EMR-5000-2B1CA1 plugs into motor protection workflows with compatible base relays (EMR-4000) and uses removable terminals for straightforward wiring. Projection mounting supports space-constrained cabinets, while the 8/9 IO combination enables existing control systems to integrate protection logic without a full panel redesign.
This relay supports Modbus TCP and DNP3 TCP/UDP communications over Ethernet RJ45, enabling seamless integration with SCADA, HMI, and industrial gateways. Use these protocols to gather protection events, metering data, and status from remote motor assets.
Key protections include Voltage Protection and Metering, Current Protection and Metering, Differential Protection, and Power Protection and Metering. Zone Selective Interlocking further reduces downtime by isolating faults to the smallest possible zone, preserving other equipment and reducing ripple effects on the line.
