Quick Summary

Eaton transformer relay is designed to protect and monitor power transformers in industrial networks. Engineers face challenges when integrating protection devices into existing control systems without compromising reliability or security. Exact certification details for this model should be confirmed with Eaton, though transformer protection relays in this family typically align with CE marking and IEC standards; verify via Eaton datasheet. This solution combines flexible Ethernet-based communication with broad I/O, enabling rapid fault isolation and proactive diagnostics, which translates to reduced downtime and lower maintenance costs across distributed transformer assets.

Ethernet-based protection and communications enable seamless integration with SCADA and substation networks, allowing centralized monitoring and remote diagnostics that improve incident response time. The business impact is faster fault localization and reduced mean time to repair, particularly when deployed in substations or maintenance-driven transformer fleets. Application: transformer protection and condition monitoring in industrial plants. Flexible I/O with 8 digital inputs, 9 digital outputs, and 2 current sensing inputs supports customizable protection schemes, alarms, and interlocks, delivering scalable control—ideal for feeder protection and remote signaling. The business impact is a lower wiring complexity and enhanced testability, enabling easier retrofit into legacy panels. Power supply range of 19-300 VDC and 40-250 VAC at 50/60 Hz ensures global site compatibility, reducing regional variants and simplifying procurement. Application: multi-site deployments with mixed power standards. Removable terminals and semi-flush mounting streamline field wiring and service, cutting commissioning time and delivering faster project ROI. Zone selective interlocking (2 zones) and integrated metering/differential sensing improve selective tripping and fault localization, minimizing outage area and downtime. Application: transformer banks and critical feeders in industrial facilities. I/O options like IRIG-B, Trip Coil Monitor, URTD Interface, and Sensitive Ground Input extend protection versatility, supporting integration with time synchronization and advanced protection schemes. Warranty and support, coupled with Eaton’s established compliance program, provide ongoing value and predictable lifecycle management for mission-critical transformer protection.

FAQs

Installation supports removable terminals and semi-flush mounting, which simplifies field wiring and retrofits. Plan for eight digital inputs and nine outputs, two current sensing inputs, and the preferred mounting layout to minimize panel space and wiring complexity. Ensure power is within the 19-300 VDC or 40-250 VAC range and that Ethernet communication lines are correctly terminated for 61850, Mbus TCP, or DNP3 TCP/UDP.
Key specs include 8 digital inputs, 9 digital outputs, 2 current sensing inputs, power supply range of 19-300 VDC or 40-250 VAC, and a 50/60 Hz operation. Communications options cover 61850, Mbus TCP, and DNP3 TCP/UDP over Ethernet RJ45, enabling modern SCADA integration and remote diagnostics.
Yes, it is designed for transformer protection with features like zone selective interlocking and metering/differential protection capabilities. Its Ethernet-based protocols and multi-IO configuration support integration with substation automation systems, remote monitoring, and fast fault isolation in feeder transformers and transformer banks.
Compliance details are provided by Eaton and can include CE marking and IEC-based standards for industrial equipment. The exact certifications should be confirmed in the product datasheet or by Eaton technical support to ensure alignment with your regional regulatory requirements.
The relay provides remote diagnostics, scalable protection, and Ethernet-based monitoring, which reduces downtime and speeds fault resolution. The one-year warranty (or 18 months from shipment, per Eaton policy) adds predictable lifecycle costs, while integration with SCADA and time synchronization features helps reduce ongoing maintenance labor and spares stocking.
