Eaton Specification Sheet - ETR-5000-2B1KA0
The ETR-5000-2B1KA0 offers eight digital inputs and nine outputs, enabling comprehensive protection logic and alarms while reducing panel wiring and simplifying configuration. This translates to faster fault isolation and improved reliability for transformer feeders and associated switchgear, with two analog inputs and two analog outputs supporting voltage and current metering for precise protection decisions. The Modbus and DNP3 TCP over LC duplex fiber optic Ethernet provide secure, low-latency data exchange to SCADA systems, shortening integration time and enabling remote diagnostics. I/O options including Trip Coil Monitor, IRIG-B, Sensitive Ground Input, and URTD Interface enhance synchronization, trip timing accuracy, and fault indication across protection modules. The power supply range of 19-300 Vdc and 40-250 Vac, plus 50/60 Hz operation, ensures compatibility with diverse plant power systems. Removable terminals and semi-flush mounting simplify installation and maintenance in existing panels, while the device’s robust design supports OEM and utility deployments with reliable long-term protection.

FAQs
Plan power inputs to 19-300 Vdc or 40-250 Vac and connect eight digital inputs, two analog inputs, and two analog outputs per the protection logic. Mount semi-flush with removable terminals for quick wiring. Integrate Modbus or DNP3 TCP over fiber, and ensure the base relay matches the ETR-4000 family. Verify Trip Coil Monitor and URTD interface connections for coordinated protection.
Key specs include eight digital inputs, nine outputs, two analog inputs, two analog outputs, and a power supply range of 19-300 Vdc or 40-250 Vac at 50/60 Hz. It supports multiple sensing schemes—current, voltage, power, and differential protection—with up to 2 current sensing inputs. Communication is via Modbus/DNP3 TCP over fiber, enabling remote monitoring and integration with SCADA.
Ideal for utilities, data centers, manufacturing facilities, and OEM transformer protection applications. It supports transformer protection, metering, and coordination within protection schemes, making it suitable for substations, switchgear, and OEM equipment where reliable remote diagnostics and scalable I/O are valued.
Compliances field indicates contact Manufacturer for region-specific certifications. Ensure regional approvals align with your market requirements (CE/UL/SIL as applicable). The device is designed for transformer protection and supports standard industry practices, but certification status should be confirmed with Eaton for your jurisdiction.
Removable terminals and modular I/O reduce maintenance downtime and simplify retrofits. The fiber-based communication and remote diagnostics minimize field visits, lowering OPEX. ROI is driven by improved fault isolation, reduced outage times, and easier integration into existing protection architectures, especially when upgrading from legacy relays or expanding protection coverage.
