Eight digital inputs and nine digital outputs provide wiring flexibility while two analog inputs and two analog outputs support signal conditioning, reducing external modules and panel wiring. This consolidated I/O set lowers installation time and improves real-time fault visibility, making it ideal for transformer protection in substations, OEM switchgear, and standalone protection panels. The dual power supply range of 19-300 Vdc and 40-250 Vac with 50/60 Hz compatibility eliminates the need for multiple adapters, simplifying retrofits and new builds across mixed-voltage facilities. I/O options including Sensitive Ground Input, Trip Coil Monitor, URTD Interface, and IRIG-B enhance signaling accuracy and time synchronization for coordinated protection schemes. A comprehensive sensing suite—Differential Protection, Power Protection with Metering, Voltage Protection with Metering, and Current Protection with Metering—delivers detailed fault signatures and energy data for compliance reporting and rapid diagnostics. Removable terminals and projection mounting shorten wiring times and facilitate quick device replacement, while the built-in diagnostics and 1-year warranty (18 months from shipment) bolster maintenance planning and asset uptime.

FAQs

Plan for projection mounting with removable terminals to ease field wiring. Ensure compatible power supply: 19-300 Vdc or 40-250 Vac, and verify 50/60 Hz operation. Allocate space for eight digital inputs, nine digital outputs, two analog inputs, and two analog outputs, plus RS-485 wiring for Modbus RTU or DNP3 RTU communication.
It supports differential protection, power protection with metering, voltage protection with metering, and current protection with metering. The device includes 8 digital inputs, 9 digital outputs, 2 analog inputs, and 2 analog outputs, enabling integrated protection logic, event logging, and accurate energy reporting for transformers in substations and OEM panels.
Yes. The ETR-5000-2B2BA1 communicates over RS-485 using Modbus RTU or DNP3 RTU, making it suitable for SCADA, energy management, and substation automation systems while supporting remote diagnostics and centralized monitoring.
Compliance status is provided by the manufacturer; check Eaton’s datasheet for the ETR-5000-2B2BA1. While CE marking and IP-rated enclosure are common for protection relays, verify exact certifications with Eaton to ensure regulatory alignment for your project and location.
Integrated protection, metering, and communications reduce the need for multiple devices and wiring, lowering installation time and spare parts. The device’s diagnostics improve mean time to repair, while the one-year warranty (18 months from shipment) supports asset reliability and predictable maintenance budgeting.
