FAQs

Plan for a projection-mounted enclosure with removable terminals to simplify wiring. The unit supports a wide power range (19–300 Vdc, 40–250 Vac) and fiber optic Modbus RTU/DNP3 RTU communications, enabling long-distance connections to SCADA. Ensure adequate space for connections and proper grounding; verify URTD/IRIG-B interfaces if time synchronization is required.
Key specs include 8 digital inputs, 9 digital outputs, 2 analog inputs, 2 analog outputs, 19–300 Vdc and 40–250 Vac power supply, and a 50/60 Hz frequency rating. Phase currents supported are 5 A or 1 A, with topology designed for transformer protection, metering, and differential protection. The device supports Modbus RTU or DNP3 RTU over fiber optic connections.
Yes. The ETR-5000-2B3FB1 is designed for Modbus RTU or DNP3 RTU over fiber optic ST, with URTD interface options and IRIG-B time reference. This enables secure, synchronized remote monitoring and integration with SCADA systems across distributed transformer assets.
The data shows Compliances: Contact Manufacturer, and no explicit SIL, CE, or IP ratings. For regulatory compliance in your facility, confirm the exact certifications with Eaton prior to procurement and installation to meet local safety and industry standards.
The device consolidates protection, metering, and communication into a single relay with 8 inputs and 9 outputs, supporting zone selective interlocking and differential protection. This can lower downtime, improve protection coordination, simplify integration with SCADA, and reduce maintenance costs through on‑board diagnostics and robust fiber-based communications.
