Quick Summary

ETR-5000-2B2LA1 is a transformer relay that protects and monitors power transformers in industrial networks. Engineers often struggle to coordinate protection, metering, and remote communications within substations, which can delay fault isolation and increase downtime. This unit supports flexible deployment with features like 8 digital inputs, 9 outputs, 2 analog inputs and 2 analog outputs, and communications over Mbus TCP or DNP3 TCP/UDP over LC duplex fiber. Compliance and regional approvals vary; confirm certifications such as CE, UL, and related IP ratings with Eaton to ensure fit for your plant. Mounted in projection devices, with removable terminals and a power range of 19-300 Vdc / 40-250 Vac, it enables scalable protection schemes and remote diagnostics for OEMs and utilities, reducing downtime and maintenance costs.

FAQs

Install with the projection mounting method and use the removable terminals to ease wiring. Plan for 19-300 Vdc or 40-250 Vac power, connect 8 digital inputs, 9 outputs, and 2 analog inputs/outputs as required by your protection scheme. Use the LC duplex fiber Ethernet link for Mbus TCP or DNP3 TCP/UDP communications and verify proper grounding and DIN rail or panel mounting compatibility.
Key specs include power supply range 19-300 Vdc / 40-250 Vac, 50/60 Hz operation, 8 digital inputs, 9 digital outputs, 2 analog inputs, 2 analog outputs, and communications via Mbus TCP or DNP3 TCP/UDP over LC fiber. Ensure phase current options of 5A or 1A are suitable for your CTs and confirm compatible sensor wiring and protection logic with your system architecture.
Yes, the ETR-5000-2B2LA1 is designed as a transformer protection relay with metering capabilities. It supports differential protection, current and voltage protection with metering, and up to 8 inputs and 9 outputs to implement zone selective interlocking and remote diagnostics in OEM equipment and power distribution panels.
Compliances are listed as manufacturer-verified; confirm regional approvals with Eaton. Specifically verify CE, UL, IP ratings, and SIL considerations where applicable for your market and installation. This ensures the relay meets local safety, environmental, and performance requirements before commissioning.
Remote monitoring via Mbus TCP or DNP3 reduces field visits and enables proactive maintenance.
