Eaton Specification Sheet - EMR-5000-2B0GB1
Feature → Business Impact → Application: Modbus RTU or DNP3 RTU over D-Sub RS-485 enables seamless integration with existing SCADA and PLC systems, reducing commissioning time and improving diagnostics across motor-driven systems in manufacturing lines. This connectivity supports remote monitoring and fault reporting, leading to faster maintenance decisions and reduced downtime in plants. Application: motor protection and drive control in control panels and substations. Feature → Business Impact → Application: Analog inputs 2 and analog outputs 2, plus digital I/O 8/9, provide richer real-time sensing and control without adding external modules, cutting panel complexity and wiring costs. This is ideal for medium-voltage motor protection schemes and energy metering in process lines. Feature → Business Impact → Application: Sensing inputs including voltage protection, current protection, differential and power metering improve protection accuracy and selectivity, delivering improved fault isolation and safer startup sequences in critical pumps and fans. Application: machine rooms and outdoor substations requiring reliable protection and metering. Feature → Business Impact → Application: Removable terminals and projection mounting simplify installation, testing, and field servicing, reducing commissioning time by hours and enabling quick retrofit to existing EMR-4000 bases. Application: retrofit projects and new builds where fast installation and serviceability matter. Feature → Business Impact → Application: Zone selective interlocking (1) enhances coordination between feeders, reducing breaker wear and improving system reliability in complex motor starter applications. Application: large motor arrays in packaging and material handling. Feature → Business Impact → Application: 50/60 Hz compatibility ensures reliable operation across global facilities, supporting multinational installations and standardizing protection schemes.

FAQs
The EMR-5000-2B0GB1 uses removable terminals and projection mounting for straightforward installation. Connect power sources in the 19–300 Vdc or 40–250 Vac range, wire the 8DI/9DO and 2AI/2AO as required, and route RS-485 Modbus RTU or DNP3 RTU lines to your PLC. The modular base (EMR-4000) supports quick retrofits and minimizes downtime during panel upgrades.
Key specs include 50/60 Hz operation, phase current options of 5A and 1A, 2 analog inputs and 2 analog outputs, 8 digital inputs and 9 digital outputs, and communication via Modbus RTU or DNP3 RTU over D-Sub RS-485. The unit is designed for integration with motor protection schemes and metering functions within industrial drives.
Yes, EMR-5000-2B0GB1 supports zone selective interlocking (ZSI) with a 1-channel configuration, enabling coordinated protection across feeders. This reduces unnecessary trips, lowers arc-flash risk, and extends motor life in complex motor arrays typical of packaging, material handling, and process lines.
The relay supports Modbus RTU or DNP3 RTU communications over D-Sub RS-485, enabling seamless integration with most PLCs and SCADA systems. This facilitates remote monitoring, fault reporting, and easier data collection for energy analytics and protection schemes.
Warranty is Eaton’s policy: one year from installation or eighteen months from shipment, whichever comes first (Policy 25-000). Compliances are listed as 'Contact Manufacturer'; verify CE, SIL, IP ratings directly with Eaton to ensure project-specific regulatory alignment.
