FAQs
The EGR-5000-2B1IB1 uses removable terminals and projection mounting for straightforward integration with existing protection schemes. It supports 19-300Vdc or 40-250Vac power and 50/60 Hz operation, making it compatible with a wide range of generator sets and control panels. For best results, match the device’s I/O counts (8 digital inputs, 9 outputs, 2 analog inputs, 2 analog outputs) with your protection logic and ensure RS-485 Modbus wiring is correctly terminated at the network edge.
It provides generator protection and monitoring capabilities with digital and analog IO for protection logic, zone selective interlocking, and trip-coil monitoring. RS-485 Modbus communication enables remote supervision, while the 50/60 Hz support ensures compatibility with standard utility and industrial power systems. The conformal-coated circuit boards improve reliability in harsh environments, reducing maintenance needs.
Yes. The EGR-5000-2B1IB1 is designed for generator protection in both standby and prime applications. Its flexible power inputs, robust protection logic, and industry-standard communications (RS-485 Modbus) support rapid fault detection and reliable operation across diverse load profiles and reliability requirements.
The data provided lists Compliance as 'Contact Manufacturer,' so regional certifications (for example CE or UL) may vary by version and installation. For exact certification status and available compliant variants, consult Eaton’s documentation or contact Eaton directly to confirm regional approvals for your location and application.
The product warranty follows Eaton’s policy: one year from installation or eighteen months from shipment, whichever occurs first. The inclusion of conformal coating, removable terminals, and modular I/O simplifies maintenance and reduces field service time, contributing to lower total cost of ownership and improved asset availability.
