Eaton EMR-3000-2A0IA1 Motor Relay - RS-485 & Ethernet
Part Number: EMR-3000-2A0IA1
Quick Summary
Eaton EMR-3000-2A0IA1 motor relay enables remote motor control and protection in industrial automation applications. Engineers often struggle to integrate motor control across RS-485 and Ethernet networks while meeting protection and metering needs. In many markets, CE marking, UL safety certifications, and RoHS-compliant materials are standard expectations; verify with the manufacturer for your jurisdiction. This device integrates seamlessly into industrial networks, leveraging Modbus RTU over RS-485 and Modbus TCP over Ethernet, while offering IRIG-B URTD interface options to support precise timing and monitoring. By combining current protection and metering with flexible I/O and robust mounting, it delivers measurable business value in reliability, safety, and operational efficiency.

Eaton Specification Sheet - EMR-3000-2A0IA1
The EMR-3000-2A0IA1 uses RS-485 Modbus RTU and Ethernet TCP Modbus for flexible remote control and data exchange, reducing panel wiring and enabling centralized monitoring across distributed motor systems in modern plants. This translates to faster diagnostics, improved uptime, and easier fleet management through standard industrial protocols and familiar control architectures. It supports current protection and metering with 5A and 1A phase ratings, delivering actionable energy use data and safer motor operation, which helps lower operating costs and extend equipment life. The IRIG-B URTD interface adds time synchronization capabilities, enabling precise coordination with other protection devices and control systems in power-heavy environments. With 4 digital inputs and 4 digital outputs plus 1 analog output, it provides rich I/O for status, interlocks, and remote signaling, improving control fidelity and reducing wiring complexity. The 50/60 Hz electrical rating and projection mounting simplify integration into existing installations, while the compact footprint (11 in L x 12 in W x 10 in H) and 8.88 lb weight ease cabinet fitment. In practice, engineers gain faster deployment, scalable motor management, and a safer, more energy-aware operation across motor fleets.

FAQs
Plan for projection mounting and available space within the panel. The device measures 11 in L × 12 in W × 10 in H and weighs 8.88 lb, with a wiring footprint supporting 19-300 VDC and 40-250 VAC inputs. Utilize the four digital inputs and four digital outputs plus one analog output for status, interlocks, and signaling; ensure proper clearance and ventilation in the enclosure.
The EMR-3000-2A0IA1 supports Modbus / DNP3 RTU over RS-485 and Modbus / DNP3 TCP over Ethernet RJ-45, enabling flexible integration into existing control networks. It also offers an IRIG-B URTD interface for time synchronization, which is critical for aligned protection schemes and accurate event timing in power and motor management systems.
Yes. The device includes current protection and metering capabilities (5A, 1A phase current) and digital/analog I/O to monitor and control motor circuits. Its 50/60 Hz rating and modular I/O allow centralized monitoring, reducing downtime and enabling precise energy accounting across motor fleets in manufacturing or process environments.
Warranty terms follow Eaton’s policy 25-000: one year from installation or 18 months from shipment, whichever occurs first. Support typically includes access to Eaton’s technical resources, product documentation, and firmware updates where applicable, with recommended service windows aligned to plant maintenance cycles to minimize impact on operations.
Key specs to consider include 5A/1A phase current, 50/60 Hz operation, projection mounting, dimensions (11 in × 12 in × 10 in), weight (8.88 lb), 4 digital inputs, 4 digital outputs, 1 analog output, 0 analog inputs, and RS-485 Modbus RTU plus Ethernet TCP Modbus. Ensure enclosure suitability, power supply compatibility (19–300 VDC / 40–250 VAC), and network integration with your SCADA or DCS.
