FAQs

This model is designed to be compatible with the ETR-4000 base relay. Verify wiring per the current Eaton installation guide, confirm terminal type is removable, and ensure the power supply range (19-300 Vdc, 40-250 Vac) and communication interface (Profibus-DP over D-Sub/RS-485) are wired according to the diagrams. The 8 digital inputs, 9 outputs, and 2 current sensing inputs should be mapped to the same protection logic as the legacy unit during the retrofit.
The relay provides current, voltage, differential, and power protection and metering across 8 digital inputs, 9 digital outputs, and 2 current sensing inputs. It supports zone selective interlocking (2 zones) and can monitor a Trip Coil, Sensitive Ground Input, URTD interface, and IRIG-B timing. This combination enables coordinated protection schemes, precise timing, and comprehensive diagnostics for transformer protection and metering.
Yes, the ETR-5000-2A2EA1 supports Profibus-DP over D-Sub/RS-485. Wire the D-Sub connection to your PLC or SCADA network according to the Eaton wiring diagrams and the Profibus-DP specifications. This enables reliable, field-grade communication for protection status, metering data, and control signals without additional interface modules.
Compliance details should be confirmed with Eaton for your jurisdiction. In transformer protection applications, look for CE marking for European compliance, SIL readiness where applicable for safety-critical protection schemes, and appropriate IP enclosure ratings to suit your environment. The product notes indicate Compliances as ‘Contact Manufacturer,’ so verify exact certifications with Eaton during procurement.
The device consolidates protection, metering, and diagnostics into a single relay, reducing panel space, wiring, and maintenance overhead. With 8 inputs and 9 outputs plus multiple protection functions, you can improve outage recovery times and coordinate protection more effectively, leading to lower unplanned downtime and better asset protection. The warranty period (one year from installation or 18 months from shipment, as per Eaton policy) provides initial risk mitigation during deployment.
