Eaton Specification Sheet - EMR-4000-2A1GB1
Wide input ranges and integrated protection enable a single device to replace multiple relays, reducing panel complexity and inventory while improving reliability and uptime. This translates to lower maintenance costs and faster troubleshooting in automation cells, with the added benefit of RS-485 communication for remote monitoring and PLC integration. The EMR-4000-2A1GB1 supports 19-300Vdc and 40-250Vac input, making it adaptable across diverse motor applications and regional power standards, enabling leaner SAGE and engineering processes in manufacturing environments. The 8 digital inputs, 5 digital outputs, and 4 analog outputs provide flexible logic and signaling for sequencing, interlocks, or sensor feedback, reducing external wiring and potential fault points. Modbus/DNP3 RTU over D-Sub RS-485 simplifies PLC/scada connectivity, accelerating commissioning and reducing project risk. Conformal coating enhances reliability in harsh environments, while zone selective interlocking (1) helps minimize fault propagation in power circuits. These features collectively support improved energy protection, metering accuracy, and compliance with industry best practices in industrial motor control.

FAQs
Follow standard panel wiring practices: mount the unit in a clean, ventilated enclosure, connect the RS-485 Modbus/DNP3 lines via D-Sub, and route I/O signals to compatible PLCs. Ensure voltage supply falls within 19-300Vdc or 40-250Vac ranges and apply conformal coating if the environment is moisture-prone or corrosive.
Use the D-Sub RS-485 interface to establish a Modbus or DNP3 RTU link with your PLC or SCADA system. Configure the device’s digital/analog I/O to match the control logic, and leverage its metering inputs for energy/voltage protection data within your automation network.
Yes. The product features conformal coating and supports rugged panel deployments, broad input ranges, and a comprehensive I/O set, making it suitable for challenging industrial sites where vibration, dust, or humidity are concerns.
It includes current protection and metering, voltage protection and metering, and power protection and metering to support safe motor operation and energy monitoring within automation panels. This enables more accurate fault detection and energy management alongside standard motor control.
Warranty terms follow Eaton’s policy: one year from the date of installation or eighteen months from shipment, whichever occurs first. For ongoing support and firmware or safety updates, contact Eaton or your authorized distributor for guidance and service options.
