Eaton ETR-5000-2B2EB1 Transformer Relay - RS485/Profibus
Part Number: ETR-5000-2B2EB1
Quick Summary
The Eaton transformer relay ETR-5000-2B2EB1 protects power transformers and feeder circuits in industrial automation environments. Engineers often struggle to configure accurate protection and timely fault isolation across multi‑voltage systems. Certification details such as CE marking, SIL safety ratings, and IP ratings should be confirmed with the manufacturer; Eaton provides these in datasheets for transformer protection relays. This solution supports Profibus-DP over D-Sub / RS‑485, delivers scalable I/O, and aligns with existing control architectures to minimize integration risk. In practice, this means faster commissioning, reduced wiring errors, and clearer protection coordination across transformers. Customers also benefit from documented warranty support and reliable field service.

Eight digital inputs, nine outputs, and two analog I/O channels enable sophisticated transformer protection logic without external expanders. This dense I/O topology translates into faster wiring, fewer junctions, and tighter fault signaling, which reduces miscoordination and downtime. In practice, you can implement differential protection, metering, and alarm sequences on a single device for transformers, switchgear feeders, and downstream bus connections. Power-supply flexibility allows for global deployment; the wide 19–300 Vdc and 40–250 Vac range, plus 50/60 Hz operation, lets you consolidate spares and simplify procurement across sites. The ProfiBus-DP over D-Sub / RS-485 interface, along with I/O options like IRIG-B, URTD, Trip Coil Monitor, and Sensitive Ground Input, streamlines PLC/SCADA integration and shortens commissioning cycles. Removable terminals, projection mounting, and conformal-coated circuitry improve field wiring reliability and serviceability in harsh environments. Base-relay compatibility with ETR-4000 provides a clear upgrade path, while Zone Selective Interlocking (2 zones) enhances protective discrimination, reducing the impact of faults on critical feeders. A robust warranty framework (1 year from installation or 18 months from shipment) supports long-term maintenance budgeting and predictable downtime costs.

Begin with ensure proper panel space and ventilation, then mount the device using the projection mounting method. Use the removable terminals to connect 8 digital inputs, 9 outputs, 2 analog inputs and 2 analog outputs. Verify the 19–300 Vdc / 40–250 Vac supply, and connect the PROFIBUS-DP/RS-485 interface to the PLC. After wiring, perform a thorough integrity check and reference the Eaton datasheet for commissioning steps.
The unit provides 8 digital inputs, 9 digital outputs, and 2 analog inputs plus 2 analog outputs. It also supports I/O options including IRIG-B, URTD Interface, Trip Coil Monitor, and Sensitive Ground Input, enabling comprehensive protection signaling, metering, and fault reporting within a single chassis.
Yes. The ETR-5000-2B2EB1 features PROFIBUS-DP over D-Sub / RS-485 for robust communication with PLCs and SCADA systems, reducing integration risk and enabling coordinated protection schemes across transformer assets.
Ideal for transformer protection in substations and on industrial feeders, including systems requiring zone selective interlocking, differential protection, and metering. Its wide supply range and modular I/O facilitate deployment across global facilities with varied voltages and control architectures.
