Quick Summary

Eaton transformer relay ETR-5000-2A3EB0 protects transformer-based power systems in industrial automation. Engineers often battle nuisance trips and slow fault diagnosis when protection isn't tightly integrated with sensing and communications. As a transformer-protection relay, it supports Profibus-DP over D-SUB/RS-485 and wide voltage ranges to simplify panel design. Compliance details are provided by the manufacturer; verify CE marking, IP protection, or SIL credentials with Eaton for regulated environments. In short, it combines robust transformer protection, flexible I/O, and field-validated communication to support reliable, compliant operation. Its 8 digital inputs and 9 outputs, along with configurable protection logic, streamline engineering workflows and maintenance planning. The unit's conformal-coated circuit boards and removable terminals ease installation in harsh environments.
