Eaton ETR-5000-2A0GA0 Transformer Relay - Modbus RTU/RS-485
Part Number: ETR-5000-2A0GA0
Quick Summary
Eaton transformer relay is a protection device that monitors transformer health and protects power systems. Engineers often face challenges achieving fast, accurate fault detection across transformer assets in modular substation architectures. Certification details vary by region; consult Eaton’s specification sheet for CE, SIL, and IP ratings or confirmation per model. The device combines 8 digital inputs, 9 outputs, and 2 current sensing inputs with robust mounting and wiring options to simplify installation. In practice, this translates to improved reliability, reduced downtime, and lower total cost of ownership for transformer protection and metering.

FAQs
Install the unit using the removable terminals and the semi-flush mounting method for a clean, serviceable panel. Wire eight digital inputs and nine outputs to your control logic, connect the power supply range of 19-300 Vdc or 40-250 Vac, and attach the RS-485 communication line for Modbus RTU or DNP3 RTU. Ensure proper grounding and route the IRIG-B or URTD options if used.
The device provides eight digital inputs, nine outputs, and two current sensing inputs, enabling comprehensive protection schemes across current, voltage, and differential protections. It supports Sensing inputs for current and voltage protection and meters, plus Zone Selective Interlocking for coordinated tripping, which reduces arc flash risk and improves reliability in transformer protection and metering applications.
It supports Modbus RTU or DNP3 RTU over RS-485 via D-Sub connectors, facilitating direct integration with most SCADA and DMS platforms. The URTD Interface option and IRIG-B trip monitoring provide additional integration flexibility, while the removable terminals simplify field wiring during retrofits or panel upgrades.
Compliance details are supplied by Eaton and may vary by region. Refer to the Eaton specification sheet for CE, SIL, and IP-related ratings specific to the ETR-5000-2A0GA0. If you require formal certification documentation for a project, request it from Eaton’s technical support or your regional distributor.
Warranty follows Eaton policy 25-000: one year from installation or 18 months from shipment, whichever comes first. For ROI, the relay enables rapid fault detection, reduces downtime, and lowers maintenance costs with remote diagnostics and integrated protection features, while simplifying replacement parts and field service through modular, removable terminals.
