FAQs
Install the EGR-5000-2A1IA0 using its semi-flush mounting and removable terminals for straightforward cabling. Plan DI/DO wiring to match the 16 digital inputs and 9 outputs, and verify RS-485 comms wiring for Modbus integration. Ensure enclosure clearance and proper grounding, then perform functional tests to confirm Trip Coil Monitor and IRIG-B options are ready for commissioning.
The relay supports a power supply range of 19-300 Vdc and 40-250 Vac, operates at 50/60 Hz, and includes 2 current sensing inputs. It provides 16 digital inputs and 9 digital outputs, with Modbus/DNP3 RTU over RS-485. Phase current ratings of 5A and 1A, along with zone selective interlocking, enable precise protection schemes and scalable deployment.
Yes. The EGR-5000-2A1IA0 includes Modbus communication over RS-485, enabling reliable data exchange with PLCs, SCADA, and DCS systems. This compatibility supports remote monitoring, fault reporting, and coordinated protection actions across multiple devices, reducing onsite maintenance and enabling unified protection logic across the plant network.
Compliance specifics are provided by the manufacturer; the product indicates Compliances: Contact Manufacturer. For certification-sensitive projects, confirm required approvals (e.g., CE or other regional standards) with Eaton prior to deployment. The unit also includes a standard warranty of one year from installation or eighteen months from shipment, whichever occurs first.
The relay improves uptime by delivering reliable protection and rapid fault isolation via 16 DI/9 DO, current sensing, and zone selective interlocking. RS-485 Modbus enables centralized monitoring and proactive maintenance, reducing unplanned outages and spare parts costs. The combination of robust protection, easy installation, and remote diagnostics translates to lower total cost of ownership over the generator fleet.
