Eaton Specification Sheet - EMR-3000-2A1FA1
IRIG-B time synchronization and fiber optic Modbus RTU or DNP3 RTU support enable precise timing, EMI tolerance, and secure remote communications for motor protection in automation panels. This translates to faster fault isolation and reliable data exchange, reducing downtime and boosting plant uptime in complex control architectures. The 4 digital inputs, 4 digital outputs, and 1 analog output provide a compact I/O bundle for interlocks, signaling, and feedback without adding external hardware. The integrated current protection and metering capability (phase currents of 5A and 1A) supports accurate load monitoring and protection logic, simplifying compliance and reporting. Projection mounting simplifies installation in dense panels, while fiber-based communication minimizes electrical noise and enables long-distance reach. This combination improves installation efficiency, reduces wiring complexity, and enhances retrofit viability for legacy systems in industries like manufacturing and energy. Compatibility with Modbus RTU and DNP3 RTU over fiber further eases integration with existing SCADA and PLC ecosystems, addressing common objections about interoperability and legacy protocol support. Overall, EMR-3000-2A1FA1 delivers measurable gains in reliability, maintenance predictability, and operational insight for motor-driven processes.

FAQs
Begin with mounting the unit using the projection method to fit your panel layout, then connect the fiber optic interface for Modbus RTU or DNP3 RTU communication. Configure IRIG-B timing if time-synchronized control is required, and wire the 4 digital inputs, 4 digital outputs, and 1 analog output to your PLC or SCADA. Verify 50/60 Hz support and ensure compliance details are confirmed with Eaton.
Key specs include 50/60 Hz operation, phase currents of 5A and 1A, 4 digital inputs, 4 digital outputs, and 1 analog output. Communications are via IRIG-B with Modbus RTU or DNP3 RTU over fiber optic ST. Sensing inputs cover Current Protection and Metering, and the device mounts via projection. These capabilities enable accurate protection, monitoring, and interlock logic within motor control schemes.
Yes, its fiber optic communications and time synchronization capabilities are designed to mitigate electromagnetic interference and support reliable remote operation. While specific IP or environmental ratings should be verified with Eaton, the integration of IRIG-B and fiber-based Modbus/DNP3 communications makes it well-suited for challenging industrial locations and retrofit projects in manufacturing and energy sectors.
Compliance details are provided by the manufacturer. Before procurement, confirm any applicable CE marking and IP/rating certifications with Eaton to meet your plant’s regulatory and safety requirements. The product page notes Compliances as Contact Manufacturer, so request the current certification status and any recent updates directly from the supplier.
The EMR-3000-2A1FA1 consolidates motor protection, metering, interlocking, and remote communications into a single device, which reduces wiring, panels space, and installation time. Fiber communication lowers EMI-related faults, improving diagnostics and uptime. Combined with programmable IO and IRIG-B timing, this yields faster fault resolution, lower maintenance costs, and clearer long-term data for performance optimization.
