FAQs

The ETR-5000-2B2EA1 supports Profibus-DP over RS-485, allowing direct integration with existing D-SUB networks and PLCs. It provides eight digital inputs, two analog inputs, two analog outputs, and nine digital outputs, consolidating protection and monitoring signals in a single device. This reduces wiring, shortens commissioning, and improves data availability for protective schemes across transformers and switchgear.
The relay integrates differential protection, power protection and metering, current protection and metering, voltage protection and metering, plus zone selective interlocking. This combination enables fast fault recognition, precise isolation, and coordinated action with upstream and downstream devices, reducing outage duration and improving system reliability in industrial automation environments.
Yes. With a broad power supply range of 19-300 Vdc and 40-250 Vac, removable terminals, and projection mounting, the unit is designed for retrofit or new installations. Its compatibility with the ETR-4000 base relay and Profibus-DP communication simplifies updating legacy protection schemes without extensive panel rewiring, accelerating a smooth transition to modern protection logic.
The product lists compliances as Contact Manufacturer, so confirm exact certifications with Eaton. In typical industrial practice, transformer protection relays are expected to align with CE marking and suitable enclosure IP ratings, and some installations may require SIL-capable logic. Always verify the specific regulatory and safety requirements for your region and application with the manufacturer.
Deploying the ETR-5000-2B2EA1 can reduce wiring, simplify panel layouts, and shorten commissioning, contributing to lower installation and maintenance costs. Built-in diagnostics and metering improve fault visibility and enable proactive maintenance. The warranty option—one year from installation or 18 months from shipment—provides defined coverage as part of the asset lifecycle strategy.
