Eaton Specification Sheet - ETR-5000-2B0IA1
Eight digital inputs and nine outputs enable complex protection schemes without external multiplexing, reducing wiring and minimizing failure points. This translates to faster fault isolation and improved reliability in transformer protection applications such as substations and service feeders. Two analog inputs and two analog outputs support current sensing and metering, enabling enhanced differential protection and energy accounting for precise protection coordination. The wide power supply range of 19-300 Vdc and 40-250 Vac ensures universal compatibility with plant power architectures, simplifying retrofits and new installations. Communication options include Modbus RTU over RS-485 and Modbus TCP over Ethernet, delivering seamless SCADA integration and real-time data visibility for power management and fault analysis. URTD Interface, Trip Coil Monitor, and IRIG-B support reinforce protection coordination and monitoring, improving ride-through reliability in zone selective interlocking schemes. Projection mounting and removable terminals ease installation and maintenance, reducing commissioning time and field labor costs.

FAQs
Yes. The device supports projection mounting and removable terminals, which simplifies retrofits in existing switchgear. With eight digital inputs, nine outputs, and two analog I/O channels, it accommodates legacy protection schemes while enabling modern communication to SCADA via RS-485 and Ethernet. This design minimizes cabin rework and reduces commissioning time on-site.
The relay provides current sensing of 5A and 1A with two analog inputs and two analog outputs for metering, plus eight digital inputs and nine outputs for protection logic. It offers Modbus RTU over RS-485 and Modbus TCP over Ethernet, enabling integration with common SCADA systems and remote monitoring platforms for real-time fault analysis.
Yes. The ETR-5000-2B0IA1 supports zone selective interlocking (2 zones) and includes differential protection capabilities through its current/voltage sensing and metering inputs. This makes it well-suited for feeder protection in substations and plant-wide protection schemes where selective tripping and fast fault isolation are critical.
Certification details are model-dependent and should be confirmed with Eaton. Industry practice for transformer relays typically includes CE marking and appropriate enclosure ratings, with SIL considerations defined by the system configuration. Always verify the exact approvals for the target installation to ensure compliance with local electrical standards.
The device consolidates protection, metering, and monitoring into a single unit, reducing wiring complexity and potential fault sources. Its remote communication capabilities enable proactive diagnostics and faster fault localization via SCADA, decreasing mean time to repair (MTTR) and improving overall plant uptime. The modular I/O and URTD/IRIG-B options support scalable protection as the plant expands.
