Quick Summary

The Eaton transformer relay ETR-5000-2B3GA1 provides robust transformer protection for industrial power distribution. Many engineers struggle to diagnose faults quickly and integrate protection relays with Modbus RTU or DNP3 networks across RS-485 interfaces. Compliance details are not explicitly listed; verify CE/SIL/IP ratings with the manufacturer for your region. This unit supports Modbus RTU or DNP3 RTU over RS-485 and operates on a wide power range of 19-300 Vdc or 40-250 Vac at 50/60 Hz, with 8 digital inputs and 9 outputs, plus analog channels for versatile protection schemes. The combination of broad I/O, time-based features, and Eaton’s warranty helps manufacturers reduce panel count, improve MTTR, and ensure reliable protection in OEM equipment and automation panels.
