Quick Summary

The Eaton transformer relay protects transformer circuits in industrial power systems, providing real-time monitoring and fault-tripping. Unplanned outages and costly repairs are common when protection relays fail to respond quickly. Certification details such as CE, SIL or IP ratings are not listed here; contact Eaton for exact certifications. The device supports Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet, 8 digital inputs, 9 outputs, and 5A/1A current sensing for scalable transformer protection. This enhances system uptime and diagnostics while simplifying integration with existing control architectures.

FAQs

Installers should mount the unit using its semi-flush mounting and connect wiring through removable terminals for easy service. With 8 digital inputs and 9 outputs, confirm correct I/O mapping to your protection logic, and use the URTD option and IRIG-B where trip verification is required. Ensure the power supply is within 19–300 Vdc or 40–250 Vac and follow the chassis labeling for safe enclosure integration.
The ETR-5000-2A0LA0 supports Mbus TCP or DNP3 TCP/UDP over LC duplex fiber optic Ethernet, enabling secure, low-latency data exchange and remote diagnostics. This compatibility facilitates integration with modern SCADA, MES, and asset management systems while maintaining robust field communications.
Yes. The device supports a power supply range of 19–300 Vdc and 40–250 Vac with a 50/60 Hz rating, allowing flexible operation across varied plant power architectures. This makes it well-suited for mixed DC/AC systems in industrial facilities and substations.
Warranty is governed by Eaton’s selling policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. For ongoing support, refer to Eaton documentation and request certification details if needed. This provides a defined support window and documented protection in capital projects.
