FAQs
The relay supports 19-300 Vdc and 40-250 Vac, with a 50/60 Hz frequency rating. This wide range allows installation across mixed plant power environments without a large number of different power supplies, simplifying retrofits and new installations while ensuring stable protection during voltage transitions.
The unit provides 16 digital inputs and 9 digital outputs, plus 2 current sensing inputs. This enables complex protection schemes, start/stop sequencing, and interlocking logic for large generator arrays, reducing miscoordination risk and improving overall reliability in standby or prime power applications.
Sensing covers Voltage Protection and Metering, Current Protection and Metering, and Differential Protection, with Zone Selective Interlocking. These features help isolate faults quickly, protect critical loads, and support accurate metering for energy management while minimizing outages and protecting equipment.
Projection mounting and removable terminals simplify mounting and servicing. The base relay is EGR-5000, enabling straightforward retrofits with existing Eaton protection ecosystems. Compatibility with IRIG-B, URTD interfaces, and RS-485 Modbus/DNP3 RTU further streamline integration with modern SCADA and control systems.
