Quick Summary

Eaton motor relay EMR-5000-2A0CB1 delivers reliable motor protection and metering for industrial drives. Engineers often struggle with integrating protection logic, diagnostics, and secure remote communications in compact control panels. Compliance information is provided by the manufacturer; where applicable, expect CE or SIL readiness and IP-related ratings to be confirmed per project. The unit supports Modbus TCP or DNP3 TCP/UDP over Ethernet RJ45 and offers 16 digital inputs, 9 outputs, and 5A/1A current sensing for scalable protection. This combination reduces wiring complexity, speeds commissioning, and improves protection coordination across motor fleets, delivering measurable uptime and lower lifecycle costs.

FAQs

EMR-5000-2A0CB1 is designed as an upgrade path from the EMR-4000 base relay, featuring removable terminals and a projection mounting method for quick field installation. Ensure the cabinet space accommodates its 8.06 in depth, 8.7 in height, and 9.72 in width; verify that the existing control wiring can be migrated to the 16 digital inputs and 9 digital outputs while preserving Modbus/DNP3 connectivity.
Key specifications include a wide input range of 19-300 VDC and 40-250 VAC, 50/60 Hz operation, and phase current options of 5A and 1A. It provides 16 digital inputs and 9 digital outputs, plus Ethernet-based communications (Modbus TCP/DNP3). Confirm compatibility with your motor’s protection needs, control logic, and network topology before deployment.
The unit supports Modbus TCP and DNP3 TCP/UDP over Ethernet RJ45, enabling SCADA integration and remote diagnostics. It also includes I/O options for local signaling and IRIG-B to support time synchronization where coordinated protection actions are required, making it suitable for plant-wide motor protection networks.
Compliances are listed as 'Contact Manufacturer' in the data set. When required, Eaton provides certification details on request, including CE marking, SIL readiness, and IP-related ratings per project. Always verify the exact approvals for your application and region before deployment.
The integrated protection and metering reduce downtime by enabling faster fault isolation and more accurate energy accounting. Removable terminals and a base-relay ecosystem simplify maintenance and retrofits, while SCADA-ready communication lowers wiring and commissioning costs. A clear warranty term supports asset management and procurement planning.
