Eaton ETR-5000-2B2CB0 Transformer Relay - Ethernet RJ-45

Flexible power and I/O configuration enables tailor-made protection; this reduces wiring complexity and panel footprint, accelerating commissioning in transformer protection schemes. The unit supports a wide power range (19-300 VDC, 40-250 VAC) and handles 8 digital inputs, 9 outputs, plus 2 analog inputs and 2 analog outputs, letting you match protection schemes to machine requirements. This translates to faster deployment across regions with varying supply standards. Industry-leading communication capabilities enable seamless SCADA integration; Modbus TCP or DNP3 over Ethernet RJ-45 supports real-time data exchange, alarms, and metering. Operators gain centralized visibility and faster fault localization, reducing MTTR. The ETR-5000-2B2CB0 also supports remote diagnostics via standard protocols, enabling proactive maintenance. Base relay compatibility with ETR-4000, conformal coated circuit boards, and removable terminals simplify retrofits and field servicing. This means technicians can swap to the new relay without a full panel rewrite, and the conformal coating provides protection in harsh environments. I/O options include Trip Coil Monitor and IRIG-B Sensitive Ground Input for coordinated protection and precise fault isolation. These features enable reliable, repeatable trip schemes essential in transformer protection in utilities and process industries. Compact footprint with 8.06 in depth, 8.7 in height, 9.72 in width, and 9.3 lb weight, combined with Eaton’s warranty, supports straightforward installation and predictable maintenance costs in modern control rooms and outdoor substations.
