Quick Summary

Eaton transformer relay is a compact protection device that monitors and protects transformer equipment in industrial power systems. Operators often confront nuisance trips due to voltage fluctuations, and this relay delivers precise differential protection to prevent unplanned outages. Typical safety requirements include CE marking and SIL or IP ratings; verify with Eaton for exact certifications. By enabling multi-parameter protection and secure communication, the ETR-5000 series supports scalable protection schemes and reduces field wiring. Key benefits include faster fault isolation, improved reliability, and streamlined maintenance for transformer protection in power distribution. Designed for harsh industrial environments, it integrates a robust 8-input, 9-output I/O matrix and supports modular expansion.

FAQs

Begin by selecting a semi-flush mounting location and ensure the panel provides adequate clearance for the 8 digital inputs and 9 outputs. Use removable terminals to simplify wiring and connect the 19-300 Vdc or 40-250 Vac power supply within the specified range. After mounting, verify IRIG-B Monitor and URTD interface options if used, and program the differential protection logic per the transformer rating.
Key specs include power supply range of 19-300 Vdc and 40-250 Vac, 50/60 Hz frequency rating, 8 digital inputs, 9 outputs, 2 current sensing inputs, and 0 analog inputs/outputs. The unit uses removable terminals and supports a semi-flush mounting method, with conformal-coated circuit boards for environmental resilience.
Yes. The device features differential protection logic designed to isolate transformer faults quickly while minimizing disturbance to healthy sections. Combined with Trip Coil Monitor and modular I/O, it provides precise protection coordination, fast fault clearance, and clear diagnostic feedback for maintenance teams in substations and industrial facilities.
The relay supports Modbus and DNP3 TCP communication over LC duplex fiber optic Ethernet, enabling robust SCADA integration. Optional I/O interfaces include IRIG-B Trip Coil Monitor and URTD Interface, which enhance time synchronization and remote monitoring for complex protection schemes.
Eaton provides a 1-year limited warranty from installation or 18 months from shipment, whichever occurs first, under the Eaton Selling Policy 25-000. Support includes access to Eaton documentation, datasheets, and direct manufacturer assistance for installation, configuration, and troubleshooting.
