Eaton Specification Sheet - EMR-4000-2A0LA1
The EMR-4000-2A0LA1 combines wide input compatibility with comprehensive protection and metering, delivering a measurable business impact by reducing unplanned downtime. Its 19–300 Vdc and 40–250 Vac operating range supports diverse motor drives, simplifying global deployment and asset standardization while the 5A/1A phase current handling ensures reliable protection without oversized hardware. This translates to smoother commissioning and lower total installed cost as engineers reuse a single device across multiple motor applications. The rich I/O set—8 digital inputs, 5 digital outputs, and 4 analog outputs—enables precise local logic, fault signaling, and data-driven control strategies, improving cycle times and reducing wiring complexity in panel layouts. IRIG-B timing and URTD interface options provide accurate time synchronization and robust external communications, essential for coordinated drives in automated lines. The Modbus and DNP3 TCP over LC duplex fiber Ethernet layer delivers noise-immune, real-time diagnostics and remote monitoring, supporting proactive maintenance and energy management programs. Zone selective interlocking further limits fault propagation, reducing equipment damage and improving overall plant safety. Compatibility with the Eaton motor-control ecosystem simplifies spare parts, firmware updates, and technician training, while the included metering capabilities enable energy use profiling for sustained efficiency gains. Common objections about integrating protection and control logic are addressed by this compact, scalable solution that consolidates motor control, protection, metering, and communication into a single device, lowering installation risk and accelerating time to value. Field-installers appreciate the compact footprint and the ability to retrofit existing lines without replacing drives, while engineers gain a unified interface for diagnostics, event logging, and remote configuration. In short, EMR-4000-2A0LA1 helps manufacturers achieve higher reliability, tighter control, and clearer operational visibility across motor-driven assets.

FAQs
EMR-4000-2A0LA1 supports Modbus and DNP3 TCP communications over LC duplex fiber optic Ethernet, providing a robust, noise-immune link to PLCs and SCADA. Use 8 digital inputs and 5 digital outputs along with 4 analog outputs to synchronize motor control with plant-wide sequencing. IRIG-B timing and URTD interface options enable precise time-stamping and external data integration. The device is designed to fit within Eaton’s E-Series ecosystem, simplifying firmware updates, diagnostics, and spare-part compatibility across existing installations.
Key specs include a wide supply range of 19–300 Vdc and 40–250 Vac, with phase current handling of 5A and 1A. The module provides current protection, voltage protection, and power protection with integrated metering. With 8 DI, 5 DO, and 4 AO, you can tailor protection and signaling to specific motors and zones. The combination supports accurate fault localization, event logging, and energy monitoring, enabling faster root-cause analysis during outages or performance anomalies.
Compliances are specified as Contact Manufacturer, so regional or industry-specific certifications should be confirmed with Eaton prior to deployment in hazardous environments. The device provides robust timing and communications capabilities, which aids in safe operation and coordinated control, but enclosure rating and regulatory approvals must be validated for your application. Plan for appropriate enclosure, labeling, and installation per local electrical codes in addition to Eaton guidance.
The product carries Eaton’s warranty policy: one year from the installation date or eighteen months from shipment, whichever comes first. Support typically includes access to Eaton’s technical resources, documentation, and product updates. For mission-critical motors, confirm regional service options and the availability of on-site support or authorized distributors to minimize downtime during maintenance or upgrades.
By combining protection, metering, and remote communications in a single device, the EMR-4000-2A0LA1 reduces panel complexity and wiring, shortening commissioning times and simplifying diagnostics. Real-time metering supports energy optimization, while zone selective interlocking minimizes collateral damage from faults. The fiber Ethernet interface improves reliability in noisy environments, enabling predictive maintenance and reduced unplanned downtime, which collectively translate to lower maintenance costs and higher plant availability.
