Eaton EGR-5000-2A1BA0 Generator Relay - RS-485 Modbus/DNP3
Part Number: EGR-5000-2A1BA0
Quick Summary
The Eaton generator relay EGR-5000-2A1BA0 provides robust generator protection for critical power systems. Engineers often struggle to coordinate protection, monitoring, and remote communication across diverse genset configurations, which can lead to extended fault diagnosis and downtime. This device supports Modbus RTU or DNP3 RTU over RS-485 and offers wide input ranges with flexible I/O, enabling precise protection timing and scalable monitoring. While compliance depends on regional approvals, Eaton can advise on CE marking, SIL readiness, and enclosure IP ratings for your installation. By combining an extensive protection feature set with SCADA-friendly communications, the EGR-5000 simplifies engineering efforts and improves reliability, maintenance planning, and total cost of ownership. It’s a proven solution for generator protection relay applications in modern industrial facilities.
