Quick Summary

Transformer relay protects transformers in power networks by monitoring protective signals and faults across critical plant assets. Engineers often struggle to get protection data into OT networks and maintain reliable remote monitoring for large, distributed systems. While compliance details for this model indicate to contact the manufacturer, transformer relays routinely address essential certifications such as CE, IP ratings, and SIL where safety-critical; confirm for your installation. With Modbus TCP and DNP3 TCP/UDP over Ethernet RJ-45, this Eaton relay integrates protection, metering, and communication in a compact package, delivering faster fault diagnosis and reduced downtime while supporting 50/60 Hz operation.

FAQs

The ETR-5000-2A0CB1 is designed to work with the ETR-4000 base as a compatible transformer protection relay family. Installation typically involves mounting the relay in a standard control cabinet, connecting the 8 digital inputs and 9 digital outputs to your protection scheme, wiring the two current sensing inputs, and configuring Modbus TCP or DNP3 over Ethernet RJ-45 for SCADA access. Removable terminals simplify field replacement, and a projection mounting option aids quick positioning in tight enclosures. Always verify terminal compatibility and boot sequence per the Eaton specification sheet before commissioning.
The device supports Modbus TCP and DNP3 TCP/UDP over Ethernet RJ-45, enabling straightforward integration with common SCADA and EMS platforms. ThisBi-directional communication allows remote monitoring, fault reporting, and control signaling, helping operators visualize transformer health and take preemptive maintenance actions without on-site visits.
Yes. The unit is designed with a power supply range of 19-300 Vdc and 40-250 Vac, plus 50/60 Hz operation, letting it adapt to mixed power environments found in modern substations and industrial facilities. This flexibility reduces additional power conversion equipment and simplifies deployment in multi-voltage sites.
The ETR-5000-2A0CB1 provides voltage protection and metering, current protection and metering, differential protection, and power protection and metering across its input/output channels. With eight digital inputs and nine digital outputs, it supports comprehensive fault detection, event logging, and accurate energy accounting for transformer assets.
