Eaton Specification Sheet - EMR-5000-2A0CA0
Feature: 16 digital inputs and 9 digital outputs enable sophisticated interlocking and status signaling for motor-driven workflows. Business impact: precise motor sequencing and fault isolation reduce nuisance trips, enabling reliable production lines. Application: conveyor systems and pump networks where complex control logic is required. Feature: Sensing inputs covering Voltage Protection, Current Protection, Differential Protection, and Power Protection and Metering provide layered protection and metered visibility. Business impact: early fault detection minimizes damage, improves safety, and enables data-driven maintenance. Application: high-load motors in continuous operation, where accurate protection improves MTBF. Feature: Ethernet-based communication with Modbus TCP or DNP3 TCP/UDP over RJ-45 supports seamless integration with PLC/SCADA and remote diagnostics. Business impact: centralized monitoring reduces on-site visits and speeds fault diagnosis. Application: modern manufacturing lines requiring scalable virtualization of protection logic. Feature: Removable terminals and compatibility with EMR-4000 base relay simplify field upgrades and maintenance. Business impact: lower installation labor costs and faster rollback in commissioning or upgrades. Application: retrofit projects and modular panel assemblies. Feature: Wide frequency and voltage range (50/60 Hz; 19–300 Vdc and 40–250 Vac) supports diverse motor applications while meeting common industrial standards. Business impact: one platform for multiple motors reduces spares inventory. Application: mixed motor fleets in processing plants and water/wastewater facilities. Feature: Zone selective interlocking and IRIG-B interface extend use in protection schemes requiring precise coordination and time synchronization. Business impact: improved coordination during faults, reducing system-wide damage. Application: high-power drives and medium-voltage motor assemblies where synchronized protection matters.

FAQs
EMR-5000-2A0CA0 is designed to mount with the EMR-4000 base and features removable terminals for easy field wiring. Plan for semi-flush mounting in standard rack heights, ensure compatible wiring ducting, and verify the Modbus or DNP3 wiring polarity to prevent communication errors during commissioning.
Verify the voltage range of 19–300 VDC and 40–250 VAC, frequency rating of 50/60 Hz, and the phase current options of 5 A and 1 A. Confirm 16 digital inputs and 9 digital outputs match your motor control logic, and ensure the Ethernet interface supports Modbus TCP or DNP3 TCP/UDP as required by the control system.
Yes. The unit provides Modbus TCP or DNP3 TCP/UDP over Ethernet RJ-45, enabling remote monitoring, integration with PLCs, and centralized protection schemes. Plan addressing and firewall rules for secure remote access and ensure your SCADA system supports the selected protocol.
Compliances are listed as 'Contact Manufacturer' for this model. Verify with Eaton for CE marking, IP rating, and any SIL requirements applicable to your installation. Always obtain the latest certification documentation from Eaton to ensure compliance with local electrical and safety standards.
Eaton provides a standard warranty policy (25-000) with one year from installation or 18 months from shipment, whichever occurs first. For maintenance, rely on the removable terminals for easier field servicing, and document the protection settings to simplify future recalibration and preventive maintenance visits.
