Eaton ETR-5000-2B1EA0 Transformer Relay - Profibus-DP RS485

Analog inputs and outputs enable local sensing, metering, and control without extra modules. This reduces wiring and cabinet space while allowing on-board measurement and quick decision-making for transformer protection. The business impact is clearer visibility and faster response, making it ideal for protection schemes in power distribution and industrial automation environments. The device offers eight digital inputs and nine digital outputs, along with zone selective interlocking. This combination decreases nuisance trips and enables coordinated protection across sections of a plant, improving reliability and uptime during fault events. With a wide power-supply range of 19-300 Vdc and 40-250 Vac, the relay accommodates diverse plant power rails, simplifying installation and reducing interconnect hardware. PROFIBUS-DP over RS-485 ensures straightforward integration with PLCs and HMI systems, cutting commissioning time and enabling centralized diagnostics. I/O options such as URTD, IRIG-B, and Sensitive Ground Input support specialized protections like trip-coil monitoring and time synchronization for mission-critical applications. The unit’s sensing inputs cover voltage, power, differential, and current protection, delivering multi-criteria protection that minimizes risk while enabling precise fault localization. Removable terminals and semi-flush mounting simplify field installation and future maintenance, lowering total cost of ownership. All these features collectively deliver measurable outcomes: faster fault isolation, reduced downtime, and streamlined integration with existing automation architectures.
