FAQs

The EMR-5000-2A0GA0 supports Modbus RTU or DNP3 RTU over RS-485, allowing seamless integration with existing PLCs and SCADA systems. It also offers 16 digital inputs and 9 digital outputs for flexible I/O expansion and remote monitoring capabilities, reducing wiring complexity during commissioning.
Differential protection compares electrical signals across motor windings to detect internal faults. When a mismatch is identified, the relay trips to isolate the motor, minimizing damage and downtime. Combined with current, voltage, and power metering, this delivers rapid fault localization and safer operation.
Yes. The EMR-5000-2A0GA0 features a semi-flush mounting method and removable terminals, which streamline panel installation, enable straightforward serviceability, and support clean, organized wiring within control cabinets.
Key specs include 19–300 Vdc and 40–250 Vac operating ranges, 50/60 Hz compatibility, and a current rating of 5A / 1A. It also includes IRIG-B I/O options and D-Sub/RS-485 communication, enabling robust monitoring and accurate time synchronization in complex systems.
Eaton provides a standard warranty of one year from installation or eighteen months from shipment, whichever occurs first. Compliance details such as CE marking, IP ratings, and SIL readiness should be confirmed with the manufacturer to ensure coverage aligns with your application and regional requirements.
