Eaton EGR-5000-2B1EA0 Generator Relay - Profibus-DP RS-485
Part Number: EGR-5000-2B1EA0
Quick Summary
Eaton generator relay protects generators in critical power systems. Engineers often struggle with nuisance trips and miscoordination that disrupt uptime. Common certifications to verify with the supplier include CE marking for electrical safety, IP-rated enclosures for harsh environments, and SIL-capable protective logic where applicable. The EGR-5000-2B1EA0 delivers Profibus-DP over D-Sub/RS-485, wide voltage ranges (19-300 VDC, 40-250 VAC), and extensive I/O for scalable protection. This combination reduces downtime, accelerates fault isolation, and enables remote monitoring for modern facilities. Designed for generator protection applications in plants, data centers, and backup systems.

The EGR-5000's power supply range of 19-300 VDC and 40-250 VAC lets a single relay cover diverse generator configurations, from small standby sets to mid-size prime gensets. This flexibility reduces spare parts and simplifies procurement by standardizing protection across multiple projects. In practice, fewer wiring schemes and a common protection platform enable faster commissioning and easier field service, improving project timelines and uptime expectations. With eight digital inputs, two analog inputs, two analog outputs, two current sensing inputs, and nine outputs, the relay supports sophisticated protection schemes without external interfaces. Zone Selective Interlocking shortens fault clearance and minimizes system-wide outages, while a Trip Coil Monitor provides deterministic control of tripping signals across the protection chain. The Sensitive Ground Input option adds resilience in electrically noisy environments, safeguarding measurement accuracy. Profibus-DP over D-Sub or RS-485 ensures reliable communication with existing PLC/SCADA networks, enabling coordinated protection and remote diagnostics. The 50/60 Hz operation and wide voltage/current sensing improve protection accuracy across generator sets, while metering and protection features provide a holistic view. Installation is simplified by semi-flush mounting and removable terminals, easing panel integration and future upgrades. The EGR-5000 base relay architecture allows easy upgrades within the same family, reducing training needs and inventory costs. Comprehensive Eaton documentation and a long-standing warranty support maintenance planning and long-term ROI for industrial facilities.

FAQs
Plan for semi-flush mounting and removable terminals to simplify panel integration. Ensure adequate space for the 8 DI, 2 AI, 2 AO, 2 current-sense inputs, and 9 DO, and wire the Profibus-DP RS-485 path with proper shielding. Verify grounding and enclosure sealing per site conditions, and configure the trip and interlock logic before commissioning.
The relay delivers voltage, current, and differential protection with 2 current-sensing inputs and 8 digital inputs for fast, reliable fault detection. Zone Selective Interlocking (1) coordinates protection schemes across sections, reducing outage scope. The Trip Coil Monitor ensures deterministic tripping, while IRIG-B and sensitive ground options enhance timing and noise immunity in challenging environments.
Yes. The EGR-5000-2B1EA0 supports PROFIBUS-DP over D-Sub or RS-485, enabling seamless integration with existing PLC/SCADA networks. It also offers multiple IO channels for local protection, plus remote diagnostics and monitoring. The documented I/O options include Trip Coil Monitor, IRIG-B, and Sensitive Ground Input for precise protection actions.
The datasheet indicates Compliances: Contact Manufacturer, so verify CE marking for electrical safety, IP enclosure ratings where applicable, and SIL capability if your safety strategy requires it. Always request Eaton's official certification documentation to confirm regulatory alignment with your facility’s standards.
A one-year warranty (or 18 months from shipment) reduces maintenance risk, while the robust protection and reduced nuisance trips lower downtime costs. The device’s modular I/O and base-EGR-5000 architecture simplify upgrades and spare-part management, delivering faster ROI through improved reliability and streamlined lifecycle management for generator protection.
