Quick Summary

Eaton transformer relay is designed to protect and monitor transformers within power distribution systems and industrial facilities. Engineers often grapple with protection miscoordination, nuisance trips, and complex wiring during relay deployments. Typical industry certifications to confirm include CE marking, SIL safety levels, and enclosure IP ratings; verify with Eaton for this specific model. The ETR-5000-2B0KB1 delivers versatile transformer protection with 8 digital inputs, 9 digital outputs, 2 analog inputs, 2 analog outputs, and a wide 19–300 VDC / 40–250 VAC power range, enabling scalable protection and metering. This offers reduced downtime, streamlined installation, and improved visibility into transformer health, while supporting Modbus/DNP3 communication and IRIG-B monitoring for modern, networked plants.

The ETR-5000-2B0KB1 provides eight digital inputs and nine digital outputs along with two analog inputs and two analog outputs, enabling integrated protection logic, metering, and signaling in a single device. This consolidation reduces panel wiring, lowers cabinet footprint, and cuts total installed cost while delivering richer fault data for faster root-cause analysis. With a broad power range of 19-300 VDC and 40-250 VAC and support for 50/60 Hz, installation across diverse plants is simplified and more consistent. Removable terminals and projection mounting make field maintenance quicker and safer, minimizing downtime during upgrades or servicing. I/O options include URTD, IRIG-B, and Trip Coil Monitor, while Modbus/DNP3 over LC duplex fiber enables secure remote monitoring and integrated cyber-resilient networking. Conformal coating on circuit boards enhances reliability in harsh environments, supporting sustained performance in transformer protection and differential protection workflows. This device also leverages zone selective interlocking (2) to improve fault-clearing speed and coordination across protection schemes.
