FAQs

The ETR-5000-2B1FB1 is designed for projection mounting with removable terminals to ease field wiring. It provides eight digital inputs, nine outputs, and two analog inputs/outputs, enabling flexible protection logic. Plan for fiber optic connections for Modbus RTU or DNP3 RTU, and confirm conduit and enclosure ratings match your site conditions. Ensure proper time synchronization interfaces, such as IRIG-B or URTD, are accessible for coordinated protection schemes.
Fiber optic communication eliminates EMI and crosstalk common in harsh electrical environments, enabling robust remote monitoring and control. Modbus RTU or DNP3 RTU over fiber ensures secure, deterministic data exchange with PLCs/SCADA. This reduces miscommunication during faults and supports faster, coordinated protection actions across distributed transformer protection networks.
Yes. The device supports a wide power range of 19-300 Vdc and 40-250 Vac with 50/60 Hz operation, accommodating diverse regional power systems. This flexibility simplifies international deployments and reduces the need for multiple relays across sites, supporting consistent protection logic and metering across the enterprise.
It provides differential protection, current protection and metering, voltage protection and metering, and power protection and metering, backed by two current-sensing inputs. With eight digital inputs and nine outputs plus 2 analog inputs/outputs, you can implement zone-selective interlocking and detailed fault diagnostics to improve reliability and fault-clearing speed.
The product is supported by Eaton documentation, including specification sheets and datasheets. Warranty terms follow Eaton policy: one year from installation or 18 months from shipment, whichever occurs first.
