FAQs
The EMR-3000-2A1CB0 uses standard mounting and offers 4 digital inputs, 4 digital outputs, and a single analog output, simplifying panel layout. Plan for RJ-45 Ethernet connectivity for Modbus or DNP3 RTU, route power within 19-300Vdc or 40-250Vac, and ensure proper grounding with the URTD interface for sensitive ground input. Verify clearance for conformal-coated circuitry in environments with dust or humidity, and consult Eaton documentation or support for any OEM-specific mounting tolerances.
Current protection and metering provide real-time current monitoring to detect overloads and abnormal loading conditions. With 5A and 1A sensing, operators can set alarms and interlocks to prevent motor damage, reduce unplanned downtime, and enable energy analytics. In high-load conveyors or pumps, this feature helps maintain consistent torque and extend motor life while supporting maintenance planning.
Yes. The EMR-3000-2A1CB0 supports Modbus/DNP3 RTU over Ethernet, 50/60 Hz operation, broad input voltages, and a robust 4/4 I/O scheme, making it suitable for packaging lines, conveyors, and automated material handling where precise timing (IRIG-B) and reliable motor protection are critical for uptime and yield.
Compliances are listed as manufacturer-verified. For regulated industries, confirm CE, UL, or SIL ratings directly with Eaton prior to deployment. If your project requires specific certifications, request the current cert package from Eaton or an authorized distributor to ensure alignment with your facility’s regulatory standards.
The EMR-3000-2A1CB0 offers centralized monitoring, reduced field maintenance, and potential energy savings from current metering. Its conformal coating and wide voltage tolerance simplify spare parts planning across mixed fleets. The one-year to eighteen-month warranty provides vendor support continuity, aiding total cost of ownership calculations and long-term reliability.
