Quick Summary

The Eaton transformer relay ETR-5000-2B0EA0 provides advanced transformer protection for power distribution and industrial automation applications. It addresses the common challenge of integrating protection, metering, and signaling within a single device, reducing wiring and commissioning time. Compliance and approvals vary by region; confirm CE, SIL, or IP ratings with the manufacturer to ensure regional regulatory alignment. By combining extensive I/O, flexible power input, and robust communication via Profibus-DP over D-SUB/RS485, this relay delivers predictable protection while enabling scalable monitoring across transformer banks. The result is lower total cost of ownership, improved diagnostics, and faster fault isolation in demanding industrial environments.

FAQs

Begin with confirming the base relay is ETR-4000 compatible, then mount the ETR-5000-2B0EA0 in a supported enclosure using semi-flush mounting. Use the Profibus-DP over D-Sub / RS-485 interface for device communication, populate the 8 digital inputs and 9 outputs, and connect the 2 analog I/O lines as required for metering and protection signals. Ensure proper termination and network addressing to avoid bus contention.
The unit offers voltage protection, current protection, and metering across sensing inputs for comprehensive transformer protection. With 2 analog inputs and 2 analog outputs plus 8 digital inputs and 9 digital outputs, you can monitor and signal multiple transformer parameters, coordinate with zone interlocking, and enable rapid trip signaling via the Profibus-DP interface.
Yes, the ETR-5000-2B0EA0 supports 50/60 Hz operation. It accepts a wide power-supply range of 19-300 VDC and 40-250 VAC, allowing installation across diverse geographic regions without needing separate power modules. This flexibility reduces inventory complexity and supports global projects.
Compliances are listed as Manufacturer contact needed for this model, so regional CE, SIL, or IP ratings must be confirmed with Eaton or an authorized distributor. When planning deployments, request current certificates or declarations of conformity for your installation locale to ensure regulatory alignment and warranty eligibility.
Deploying this relay can reduce wiring complexity by consolidating protection, metering, and signaling into a single device, lowering panel space and commissioning time. The integrated Profibus-DP communication streamlines diagnostics and remote monitoring, which translates to shorter downtime, faster maintenance response, and lower total cost of ownership over the transformer protection lifecycle.
