Quick Summary

Eaton transformer relay provides protection and monitoring for power transformers in industrial electrical systems. Without real-time monitoring, differential faults can go unnoticed, triggering outages and costly downtime. Key considerations to confirm on installation include potential SIL and CE compliance, and IP-rated enclosures—verify exact certifications in the Eaton datasheet. This model integrates 5A/1A current sensing, modular I/O, and Modbus/DNP3 TCP over fiber, delivering robust transformer protection. In practice, it reduces nuisance trips and accelerates fault isolation, supporting uptime and safety in critical facilities. With 8 digital inputs, 9 outputs, 2 analog channels, IRIG-B, URTD interface, and 50/60 Hz operation, it adapts to new or legacy protection schemes.
