Eaton Specification Sheet - EMR-4000-2A0GA0
Current protection and metering are integrated into EMR-4000-2A0GA0, delivering fast fault detection and energy accounting. This minimizes unplanned downtime and supports energy optimization in manufacturing environments. Use in heavy-duty drives to monitor current profiles and trigger protective actions without external modules. The eight digital inputs, five digital outputs, and four analog outputs provide flexible control schemes and safe interlocks, reducing panel wiring complexity and speeding commissioning in packaging and material handling lines. Modbus and DNP3 RTU communication over D-Sub RS-485, plus URTD interface and IRIG-B timing, enable seamless PLC/SCADA integration with precise time synchronization for accurate event logging. Zone selective interlocking (1) further improves fault isolation, improving safety and reducing collateral damage during faults. A one-year Eaton warranty supports long-term reliability, with compliance details available from the manufacturer as needed for your specific installation.

FAQs
What you need to know: verify supply voltage range (19–300 Vdc, 40–250 Vac) and ensure adequate clearance for mounting. Connect the URTD interface and IRIG-B timing lines as needed for time synchronization. Use the 8 digital inputs, 5 digital outputs, and 4 analog outputs to build your protection and control logic, then validate Modbus/ DNP3 RTU communications over RS-485. Follow Eaton's mounting and cabling standards to minimize EMI and ensure reliable operation.
EMR-4000-2A0GA0 supports Modbus and DNP3 RTU over D-Sub RS-485, enabling PLC or SCADA integration. It also provides URTD interface and IRIG-B timing for synchronized data logging and event correlation. These features facilitate remote monitoring, fault analysis, and driver coordination within industrial automation architectures.
Yes. The unit includes Zone Selective Interlocking (ZSI) capability, which helps isolate faults faster and prevent unnecessary tripping of adjacent equipment. This is particularly beneficial in multi-motor drives and switchgear assemblies, where selective protection improves overall plant reliability and reduces downtime during faults.
The device provides current protection and metering for 5A and 1A sensing, voltage protection and metering, and power protection and metering. It also offers 8 digital inputs, 5 digital outputs, and 4 analog outputs for flexible deployment. These features enable precise protection schemes, energy accounting, and integrated control within a single relay package.
