FAQs

EMR-4000-2A0GA1 is designed for panel-based motor protection with RS-485 Modbus and IRIG-B URTD interfaces. It offers 8 digital inputs, 5 digital outputs, and 4 analog outputs for flexible control. When integrating with E-Series equipment, ensure compatible communication wiring, standard mounting footprints, and synchronized IO sequencing to maximize diagnostic visibility and minimize panel rework.
The unit supports a wide voltage range of 19-300 Vdc and 40-250 Vac, with phase current options of 5A and 1A. It provides voltage, current, and power protection and metering, enabling precise fault detection and energy monitoring. The 8/5/4 IO set enables complex protection schemes and real-time monitoring without external modules.
Yes. The EMR-4000-2A0GA1 is purpose-built for motor protection and metering in industrial drives, including packaging and processing lines. Its integrated analog and digital I/O, IRIG-B URTD interface, and robust voltage/current sensing support reliable protection, active fault reporting, and data-driven maintenance planning, improving line uptime and process consistency.
Compliances are region-specific and Eaton recommends confirming with the manufacturer for exact certs such as CE or UL. The product carries Eaton’s standard warranty policy (one year from installation or 18 months from shipment, whichever occurs first). This provides a baseline of support for field installations and new deployments.
A typical ROI driver is reduced downtime through integrated protection and metering, plus simplified wiring with RS-485 and IRIG-B interfaces. Its 8/5/4 IO configuration supports comprehensive motor health monitoring and predictive maintenance, enabling fewer unexpected outages and lower costs for spare parts and panel space.
