Quick Summary

Eaton transformer relay is a protection device for transformer networks in industrial power systems. Engineers often struggle to coordinate protection logic, fault reporting, and remote monitoring across multiple inputs while maintaining uptime in challenging environments. Certification details should be verified with Eaton to ensure CE, SIL, or IP ratings meet your installation and compliance requirements. This solution supports transformer protection with Modbus TCP or DNP3 communications over Ethernet RJ45, enabling scalable integration with SCADA and automation systems to reduce downtime and maintenance costs.

Power supply range and voltage flexibility enable seamless integration into mixed plant environments, reducing wiring and inventory needs while supporting 19-300 Vdc and 40-250 Vac with 50/60 Hz operation. This translates to faster installation, fewer voltage mismatches, and lower commissioning costs in retrofit projects. The device offers eight digital inputs and nine digital outputs plus two current-sensing inputs, delivering robust protection schemes and metering without relying on external interfaces. With Modbus TCP or DNP3 over Ethernet RJ45, it integrates smoothly with modern SCADA and automation architectures, improving visibility and fault response times across distributed assets. Zone selective interlocking (2) enhances protection coordination, limiting arc damage and improving system reliability. Removable terminals and semi-flush mounting simplify maintenance and cabinet integration, reducing downtime during servicing. I/O options such as Trip Coil Monitor, IRIG-B, Sensitive Ground Input, and URTD Interface expand monitoring and time synchronization capabilities for critical applications. Compatibility with the ETR-4000 base allows scalable upgrades without replacing the entire protection scheme, preserving investment while enabling feature growth.

FAQs

Ensure the ETR-4000 base is present and accessible, then mount the ETR-5000-2A2CA0 using the semi-flush method. Connect the eight digital inputs and nine digital outputs to the designated field devices, and wire the two current-sensing inputs with the protected feeders. Use removable terminals to simplify future servicing and confirm the Modbus TCP or DNP3 network connection to the SCADA backbone.
The unit supports a power-supply range of 19-300 Vdc and 40-250 Vac at 50/60 Hz. It features eight digital inputs, nine digital outputs, and two current-sensing inputs (5A and 1A phase currents). Communications are via Modbus TCP or DNP3 over Ethernet RJ45, with a base relay model of ETR-4000 and multiple I/O options for extended protection.
Yes. It is designed for transformer protection with integrated metering and protection functions, and its flexible I/O, wide power range, and Ethernet communications support SCADA integration. Zone selective interlocking improves fault isolation, while multiple I/O options enhance monitoring and time synchronization for reliable performance in distribution environments.
Certification specifics should be confirmed with the manufacturer to match regional requirements. The device lists 'Compliances: Contact Manufacturer' and includes robust protection features. For your project, verify CE, SIL, IP, and any regional approvals with Eaton to ensure full regulatory compliance prior to deployment.
The product is covered by Eaton's warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. Upgrade paths leverage the ETR-4000 base, allowing scalable protection expansion without replacing the entire protection frame, which helps protect your capital investment and simplifies maintenance planning.
