Eaton generator relay EGR-5000-2B0EB0 - Profibus-DP RS-485
Part Number: EGR-5000-2B0EB0
Quick Summary
The Eaton generator relay is a protective device that safeguards generator sets in industrial and utility environments. Engineers often struggle to integrate protection logic, diagnostics, and remote monitoring across fleets of generators, which can drive downtime and maintenance costs. In practice, quickly verifying compliance and ensuring seamless communication are critical; for this model, consult Eaton for current compliance status and applicable standards. This relay supports Profibus-DP over RS-485 and offers removable I/O modules and conformal coated boards, delivering reliable protection and scalable integration for modern automation architectures. By design, it helps reduce mean time to repair and simplifies lifecycle management while aligning with core automation objectives like availability and safety.
