Quick Summary

Eaton transformer relay is a protection and monitoring device for transformer circuits in industrial facilities. Engineers often struggle with coordinating protection schemes and remote diagnostics across transformers, leading to downtime and elevated maintenance costs. The ETR-5000 family supports Modbus RTU or DNP3 RTU over RS-485 and operates on 50/60 Hz with extensive analog and digital I/O for flexible integration. While regional compliance details should be confirmed with Eaton, typical transformer protection relays align with common CE, UL, and IP-related expectations depending on installation. From panel retrofits to new substations, this device delivers robust protection, fast communication, and scalable metering, driving reliability and reducing total cost of ownership.

FAQs

Begin by mapping the 8 digital inputs and 9 outputs to your protection logic and control scheme. Use removable terminals to simplify wiring and ensure proper labeling. Verify the 19-300 Vdc or 40-250 Vac power supply is within system tolerances, then connect RS-485 lines for Modbus RTU or DNP3 RTU communication to your SCADA. Finally, perform a functional test to confirm protection logic and communications operate as intended without causing unintended trips.
The ETR-5000-2B3GB1 provides 8 digital inputs, 9 digital outputs, 2 analog inputs, and 2 analog outputs. It supports a voltage supply range of 19-300 Vdc and 40-250 Vac, with a frequency rating of 50/60 Hz. Communication is via Modbus RTU or DNP3 RTU over RS-485, enabling integration with standard SCADA systems.
Yes. Designed as a transformer protection relay, it combines protection, metering, and communication capabilities suitable for substations and industrial facilities. Its Modbus RTU and DNP3 RTU interfaces enable centralized monitoring, while the 8/9 I/O and IRIG-B/Sensitive Ground features support precise protection coordination and safety interlocking in demanding environments.
The data shows Compliances as 'Contact Manufacturer,' so verify region-specific approvals directly with Eaton. In practice, confirm CE, UL, and any IP/rating requirements with your local Eaton representative or authorized distributor to ensure the product meets your installation standards and regulatory obligations.
By consolidating protection, metering, and communication in a single device, the ETR-5000-2B3GB1 can reduce wiring complexity and spare part counts, lowering maintenance overhead.
