Feature → Business Impact → Application: Integrated motor relay with 8 digital inputs and 5 digital outputs reduces wiring complexity and panel space while simplifying device orchestration across drives. This enables faster commissioning and easier maintenance for motor-driven systems in manufacturing and process industries. Feature → Application-specific metering: Sensing inputs cover Power Protection and Metering, Current Protection and Metering, and Voltage Protection and Metering, delivering accurate energy and fault data to SCADA or PLCs, which translates to better energy management and reduced energy waste in industrial facilities. Feature → Robust communication options: D-Sub RS-485 for Modbus/DNP3 RTU, plus IRIG-B and URTD interfaces, improve data exchange, remote monitoring, and protection coordination with existing automation architectures. This minimizes integration risk and supports scalable, future-ready controls in plant environments. Feature → Zone selective interlocking: Zone selective interlocking value of 1 enhances protection coordination across feeders, reducing arc-flash exposure and miscoordination during faults. Application spans electrical rooms, motor control centers, and critical process lines. Feature → Protection and metering integration: Voltage, current, and power protection combined with meter data simplify compliance reporting and improve maintenance planning, especially for critical pumps, compressors, and fans. Feature → Physical footprint and resilience: With dimensions of 8.06 in (L) × 8.7 in (H) × 9.72 in (W) and a weight of 9.259 lb, the EMR-4000-2A1GA1 fits compact enclosures while maintaining rugged performance for harsh industrial environments. Warranty and support: Eaton’s 25-000 policy provides one year from installation or eighteen months from shipment, ensuring reliability and rapid service for mission-critical applications. Compatibility note: This device is designed to integrate with Eaton E-Series relays and PowerPort-E workflows for enhanced monitoring and protection outcomes.

FAQs

The EMR-4000-2A1GA1 is designed for motor protection and control in standard industrial panels. It offers D-Sub RS-485 Modbus/DNP3 RTU communication, IRIG-B and URTD interfaces, and 8 digital inputs with 5 digital outputs, enabling easy integration with common PLCs and SCADA systems. Confirm enclosure size and mounting compatibility in your control cabinet and consider existing Eaton E-Series compatibility for streamlined upgrades.
Key specs include 5A and 1A phase current ratings, 8 digital inputs, 5 digital outputs, 4 analog outputs, and 0 analog inputs. It supports voltage protection and metering, current protection and metering, and power protection and metering. Its voltage range spans 19-300V DC and 40-250V AC, with IRIG-B, URTD, and D-Sub RS-485 interfaces for robust communications and monitoring.
Yes. The unit includes zone selective interlocking capability (value of 1) to improve protection coordination across feeders, reducing fault impact and optimizing breaker operations. This makes it well-suited for motor centers, switchgear assemblies, and critical process lines where selective tripping improves uptime.
Compliance details are provided by the manufacturer. The product lists 'Compliances: Contact Manufacturer,' so CE, SIL, or IP ratings should be confirmed with Eaton for your installation region and project requirements. Verify any regional certification needs before deployment to ensure full regulatory alignment.
The EMR-4000-2A1GA1 consolidates motor protection, metering, and communication in a single device, reducing wiring, panel space, and commissioning time. With a one-year warranty (or 18 months from shipment, whichever occurs first), it supports predictable maintenance planning and downtime reduction, translating to lower lifecycle costs in motors and drives-heavy applications.
