Eaton Specification Sheet - EMR-3000-2A0GA1
Flexible I/O and compact integration enable reduced panel wiring and simplified installation, delivering measurable efficiency gains and lower total cost of ownership for motor control applications in conveyors, pumps, and fans. The four digital inputs and four digital outputs, plus one analog output, support nuanced control schemes, enabling precise sequencing and fault isolation in automated machinery. Current protection and metering provide real-time sensing and energy monitoring, improving protection against motor faults and enabling better energy management across production lines. Modbus and D-Sub RS-485 (RTU) interfaces simplify integration with existing SCADA and automation networks, reducing commissioning time and ensuring reliable data exchange. IRIG-B and URTD interface options deliver time-synchronized operations in power-automation environments, supporting accurate interlocks and coordinated control across distributed systems. Projection mounting and broad voltage ratings (19–300 V DC; 40–250 V AC, 50/60 Hz) offer flexible installation in standard control panels and harsh environments, underscoring ruggedness and long-term availability. A one-year Eaton warranty and the documented support policy further reduce risk and provide a clear path to troubleshooting and optimization in industrial settings.

FAQs
Yes. The EMR-3000-2A0GA1 uses a D-Sub RS-485 interface suitable for Modbus and DNP3 RTU, enabling straightforward retrofits into legacy panels. It also offers four digital inputs and four outputs to augment existing I/O without major wiring changes. Ensure panel clearance and proper shielding to maintain signal integrity in electrically noisy environments.
The relay supports phase currents of 5 A and 1 A, with current protection and metering built in for motor diagnostics. It operates from 19–300 V DC or 40–250 V AC at 50/60 Hz, giving flexibility for mixed motor feeds. Use the sensing features to monitor faults and protect motors from overloads while gathering actionable energy data.
Industries requiring synchronized operations—such as power generation, petrochemical processing, and large-scale manufacturing—benefit from IRIG-B URTD timing for coordinated interlocks and accuracy across distributed control systems. With four digital I/O lines and a dedicated analog output, the EMR-3000-2A0GA1 supports precise motor sequencing and real-time monitoring in demanding environments.
Compliance details are specified by the manufacturer. Verify CE, IP ratings, SIL, and other relevant certifications with Eaton for your installation. The product’s data indicates compliance information should be confirmed; align requirements with local regulations and your internal compliance standards before deployment.
The EMR-3000-2A0GA1 is backed by Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. Regular inspection of I/O connections, RS-485 cabling, and power supplies is recommended, with sensor and metering readings reviewed during preventive maintenance to maximize uptime and return on investment.
