FAQs

Install the ETR-5000-2B2IA1 as a transformer protection relay within your control cabinet, using the removable terminals for straightforward wiring. Map digital I/O to existing interlocks and alarms, configure RS-485 Modbus RTU or Ethernet TCP for SCADA integration, and enable Zone Selective Interlocking to coordinate tripping with upstream protection. Ensure power supply is within 19-300Vdc or 40-250Vac and verify grounding per Eaton guidelines.
The unit provides Modbus RTU over RS-485 and Modbus TCP over Ethernet RJ-45, enabling integration with standard SCADA and historian systems. Use RS-485 for local loop connections and Ethernet for remote monitoring and diagnostics. Configure IRIG-B time input for precise time stamping and leverage URTD interface for with-trip monitoring to enhance protection visibility.
Yes, the ETR-5000-2B2IA1 supports both 50 and 60 Hz systems. It accepts a broad power supply range of 19-300 VDC and 40-250 VAC, allowing flexible deployment across diverse industrial environments and easing migration from legacy protection schemes without separate power conversion hardware.
The relay is covered by Eaton’s standard warranty policy (one year from installation or 18 months from shipment, whichever occurs first). For maintenance, rely on the modular, removable terminals for quick field checks, and consult Eaton’s specification sheets and support resources to plan preventive maintenance schedules and firmware updates as needed.
ROI is driven by consolidated protection, metering, and communications in a single device, reducing cabinet footprint, wiring complexity, and maintenance labor. Enhanced remote monitoring and SCADA integration improve fault isolation and uptime, while IRIG-B accuracy and Zone Selective Interlocking reduce unnecessary outages, delivering lower lifecycle costs and faster commissioning.
