Eaton Specification Sheet - EMR-3000-2A0BB1
Wide voltage and frequency support (19-300Vdc, 40-250Vac, 50/60 Hz) enables a single device to cover diverse motor loads, reducing inventory and wiring complexity. This translates to lower installation costs and faster commissioning in global sites. Applications include motor control panels in manufacturing lines and process automation. The RS-485 Modbus/DNP3 RTU interface and URTD IRIG-B support simplify SCADA integration and time-synchronized data logging, delivering improved fault diagnostics and uptime while aligning with plant-wide data architectures. Conformal coated circuit boards enhance reliability in harsh environments, decreasing field failures in chemical plants or outdoor substations. Projection mounting simplifies panel fit and serviceability, shortening assembly time and enabling compact enclosures. Four digital inputs and four outputs plus one analog output deliver flexible I/O for motor logic, with minimal wiring and clear expandability. The current protection and metering feature provides real-time current data for load profiling and protection schemes, improving energy visibility and protective coordination across drives.

FAQs
Install the unit using projection mounting for a precise panel fit. Connect four digital inputs and four digital outputs to your existing I/O scheme, and wire the 5 A and 1 A sensing contacts for current protection and metering. Establish RS-485 Modbus or DNP3 RTU communication, and configure the IRIG-B URTD interface if time synchronization is required. Verify the conformal coating protects against environmental exposure, then perform a functional check with a simulated motor load.
The EMR-3000-2A0BB1 supports 19-300 VDC and 40-250 VAC operation at 50/60 Hz, with current protection rated at 5 A and 1 A. It includes RS-485 communication for Modbus or DNP3 RTU and the URTD IRIG-B interface for precise time synchronization. The device provides four digital inputs, four digital outputs, and one analog output for versatile motor control and monitoring tasks.
Yes. The EMR-3000-2A0BB1 communicates over RS-485 using Modbus RTU or DNP3 RTU, enabling seamless integration with common automation controllers and SCADA systems. This reduces wiring complexity, supports remote diagnostics, and aligns with enterprise data architectures, making it suitable for OEM panels, factories, and utility-scale installations.
Compliances are specified by the manufacturer; exact CE marks, IP ratings, and SIL configurations depend on the variant. To ensure regulatory and safety alignment for your installation, verify the precise configuration with Eaton and request the validated certification documentation for your region and application.
The motor relay reduces cabinet wiring, combines protection and metering in a single device, and uses conformal coating for harsher environments. These factors translate into lower maintenance costs, reduced downtime, better energy visibility, and faster commissioning. Over the equipment lifecycle, this yields a favorable return on investment in industrial motor control and automation projects.
