Quick Summary

Eaton transformer relay provides transformer protection and remote monitoring for industrial power systems. It integrates with modern control networks, reducing setup time and minimizing misconfiguration during commissioning. A common pain point is wiring complexity and slow fault diagnosis across protection, metering, and trip logic. This model supports Modbus RTU or DNP3 RTU over RS-485, giving you robust SCADA integration while preserving local protection functions. Compliance details are listed as 'Contact Manufacturer'—verify CE, SIL, and IP ratings with Eaton for your regulatory needs. With 8 digital inputs, 9 digital outputs, 2 current sensing inputs, and a wide power range (19-300 Vdc, 40-250 Vac) it delivers reliable operation, fast fault isolation, and scalable protection for transformers.
