Eaton ETR-5000-2A0GB0 Transformer Relay - Modbus RTU / DNP3 RTU over RS485
Part Number: ETR-5000-2A0GB0
Quick Summary
The Eaton transformer relay is a protective device for transformer protection in industrial power systems, monitoring current, voltage, and protection logic to prevent faults from escalating. Operators often struggle with coordinating protection trips and remote monitoring across distributed assets, leading to outages and inefficiencies. Certifications such as CE, SIL, and IP ratings are not listed in the spec; please verify with Eaton for the latest approvals and site compliance. With Modbus RTU or DNP3 RTU over RS-485 support, the device integrates smoothly with SCADA and MES platforms, delivering visibility and faster response, which translates to reduced downtime and proactive maintenance across OEM and plant environments.

FAQs
The unit uses removable terminals and supports semi-flush mounting for straightforward panel installation. Plan for eight digital inputs and nine outputs to enable comprehensive protection logic, while ensuring proper clearance for wiring of the 19-300Vdc/40-250Vac power rails and RS-485 communication to SCADA systems.
The device provides 8 digital inputs, 9 digital outputs, and 2 current sensing inputs, enabling multiple protection schemes and metering functions. This configuration supports current and voltage protection with scalable signaling to protection relays, with compatibility to URTD interfaces and IRIG-B options for time synchronization.
It supports Modbus RTU or DNP3 RTU over RS-485, allowing straightforward integration with common SCADA and MES platforms. This enables centralized monitoring, remote trip coordination, and easier asset management across distributed transformer protections.
The relay operates over a dual-range power supply: 19-300 VDC and 40-250 VAC, with a frequency rating of 50/60 Hz. This flexibility supports diverse installation environments, from retrofit projects to new builds, without requiring additional power conversion hardware.
Warranty terms follow Eaton Selling Policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. For compliance specifics and regional service options, contact Eaton or your authorized distributor to confirm current coverage and support levels.
