Eaton ETR-5000-2A0BB0 Transformer Relay - Modbus RTU
Part Number: ETR-5000-2A0BB0
Quick Summary
ETR-5000-2A0BB0 Transformer Relay by Eaton delivers robust transformer protection and real-time monitoring for power distribution panels and OEM equipment. The unit integrates Modbus RTU or DNP3 RTU communication over RS-485, supporting eight digital inputs and nine outputs for versatile protection logic. A wide power-supply range of 19-300 VDC and 40-250 VAC, plus 50/60 Hz operation, accommodates diverse plant architectures and minimizes wiring changes during upgrades. Operators often struggle to coordinate protection schemes with existing control systems and achieve fast fault isolation; this relay offers programmable logic, time-coordinated trips, and reliable communication interfaces to reduce MTTR and improve uptime. Certifications such as CE marking, SIL, and IP ratings should be verified on the latest Eaton datasheet for compliance. The conformal-coated circuit boards and optional Trip Coil Monitor enable durable field installation and long-term service.

Eaton Specification Sheet - ETR-5000-2A0BB0
Modbus RTU over RS-485 and DNP3 RTU compatibility enables seamless integration with existing SCADA and protection networks, reducing commissioning time and enhancing visibility for rapid fault localization and reduced downtime. The 8 digital inputs, 9 digital outputs, and 2 current-sensing inputs provide a flexible protection logic framework, simplifying panel wiring and enabling local trip coordination or interlocking across transformer banks. With a wide power-supply range of 19-300 VDC and 40-250 VAC and 50/60 Hz operation, the unit adapts to mixed-Voltage plants, minimizing BOM changes during upgrades. Removable terminals and semi-flush mounting streamline field installation, while conformal-coated boards boost reliability in harsh environments and across long service intervals. I/O options like URTD, Trip Coil Monitor, and IRIG-B time synchronization support advanced protection schemes and precise event timing. Compatibility with the ETR-4000 base relay preserves a clear upgrade path and spare-part alignment, reducing lifecycle costs and maintenance risk. The Eaton warranty and service policy provide predictable support, helping maintenance teams justify protective-relay investments and achieve faster ROI in mission-critical applications.

FAQs
Begin by confirming your supply is within the 19-300 VDC or 40-250 VAC range and 50/60 Hz. Mount the unit semi-flush and secure removable terminals for the 8 digital inputs, 9 outputs, and 2 current sensing inputs. Connect RS-485 for Modbus RTU or DNP3 RTU, and reference the ETR-4000 base relay as part of the upgrade path. Field-test the protection logic with a staged fault to validate timing and interlocking before commissioning.
The relay supports a broad input range: 19-300 VDC and 40-250 VAC, with operation at 50/60 Hz. This design enables compatibility with transformers powered from DC supplies or AC plants without separate adapters, reducing wiring complexity and enabling easier integration into legacy systems.
Yes. The unit combines transformer protection functions with Modbus RTU/DNP3 RTU communications over RS-485, eight digital inputs, nine outputs, and two current sensing inputs. Its ETR-4000 base compatibility, time-coordinated trips, and optional Trip Coil Monitor support ensure reliable protection coordination in substations and OEM applications, with scalable integration into existing control architectures.
Verify the CE marking, safety-related certifications such as SIL, and IP ratings on the latest Eaton datasheet. While the product data indicates general compliance, exact certification statuses are version-specific and should be confirmed to meet local regulatory requirements and plant standards.
The ETR-5000-2A0BB0 supports long-term reliability through conformal-coated boards, a durable base-relay platform, and modular I/O. Reduced downtime from faster fault isolation and streamlined integration lowers MTTR and maintenance labor. Warranty coverage (one year from installation or 18 months from shipment) provides financial protection during initial maintenance cycles.
