The ETR-5000-2A0LB1 features a broad power supply range of 19-300 Vdc and 40-250 Vac, which reduces the need for multiple power rails and simplifies panel design. Business impact: fewer power conversion points and lower wiring complexity, speeding up installation in mixed-volt environments. Application: transformer protection in facilities with diverse voltage standards and stringent uptime requirements. The unit provides 8 digital inputs and 9 digital outputs, plus 2 current-sensing inputs, enabling richer control, metering, and protection logic without external relays. Business impact: minimizes wiring errors and reduces panel footprint; Application: integrated protection and metering for transformer bays. Communication is via Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet, delivering reliable SCADA connectivity and remote diagnostics. Business impact: enhances fault visibility, reduces on-site visits, and supports scalable automation strategies. The device supports I/O options such as Trip Coil Monitor, IRIG-B, and URTD Interface, improving trip reliability and time synchronization. Application: precise protection coordination in critical feeder circuits. Conformal coating protects circuit boards in harsh environments, while removable terminals and projection mounting speed up field servicing and retrofits. These design choices translate into lower maintenance costs and faster ROI for transformer protection projects.

FAQs

Installers should plan for projection mounting and use removable terminals to simplify wiring. The unit supports 19-300 Vdc or 40-250 Vac power supplies and provides 8 digital inputs with 9 outputs, plus 2 current sensing inputs. Plan for Modbus or DNP3 TCP/UDP communication via LC duplex fiber for SCADA integration and ensure proper conformal coating for harsh environments.
Key specs include a broad power-supply range (19-300 Vdc, 40-250 Vac), 50/60 Hz operation, 8 inputs, 9 outputs, and 2 current-sensing inputs. The device supports transformer protection functions, voltage and current metering, and differential protection, with Modbus / DNP3 TCP communications for remote monitoring and control.
Yes. It is designed as a transformer protection relay with 8 digital inputs, 9 outputs, and current sensing, plus I/O options like Trip Coil Monitor and IRIG-B. Its Mbus TCP or DNP3 TCP/UDP over LC fiber Ethernet enables integration with SCADA systems, improving protection coordination and fast fault isolation in industrial transformer setups.
Compliances are to be confirmed with the manufacturer. In practice, transformer protection relays in this class are evaluated for CE marking, SIL considerations, and IP-rated enclosures depending on the installation scenario. Always verify the specific compliance documentation (datasheets, certificates) from Eaton for your region and application.
ROI is driven by reduced downtime from faster fault detection, fewer external relays due to integrated protection and metering, and easier maintenance via removable terminals and field-proven coating. The combination of remote monitoring via Mbus/DNP3, reliable trip coordination, and scalable network interfaces typically lowers maintenance costs while enhancing system uptime and data transparency.
