Quick Summary

Eaton transformer relay is a protective device for transformer protection in industrial power systems. Engineers often struggle with integrating protection relays into fieldbus networks while preserving fast, reliable trips during faults. For certifications, consult Eaton's specification sheet to confirm CE and UL and other regional approvals current to your installation. This model combines 8 digital inputs, 9 digital outputs, two current sensing inputs, and Profibus-DP over RS-485 to simplify mounting in control panels. The product supports 19-300 Vdc and 40-250 Vac power ranges and 50/60 Hz operation, enabling flexible installation across diverse assets. By consolidating protection, metering, and monitoring in one device, it reduces wiring, shortens commissioning time, and strengthens transformer protection relay performance in critical power systems.

FAQs

Begin with panel layout planning using the semi-flush mounting requirement and removable terminals for easy field servicing. Mount the unit in a suitable rack or enclosure, connect the 8 digital inputs and 9 outputs to the control circuitry, and wire the power supply within the 19-300Vdc or 40-250Vac range. Refer to the Eaton datasheet for detailed terminal assignments and wiring diagrams.
The ETR-5000-2A0EA0 provides 8 digital inputs, 9 digital outputs, and 2 current sensing inputs for protection and metering. It supports 19-300 Vdc and 40-250 Vac power, operates at 50/60 Hz, and features Profibus-DP over RS-485 for network communication. Phase current options include 5A and 1A sensing ranges, with Tripp Coil Monitor I/O available as an option.
Yes. The relay integrates Profibus-DP over D-Sub / RS-485, enabling straightforward bus communication with PLCs and SCADA systems. This supports rapid data exchange, centralized monitoring, and improved protection coordination in transformer protection deployments across substations and OEM equipment.
