Eaton ETR-5000-2B3DA0 Transformer Relay - Profibus-DP

Feature → Business Impact → Application: Wide power-supply range supports 19-300 Vdc and 40-250 Vac, 50/60 Hz, enabling deployment across varied plant electrical environments with fewer power-quality concerns and reduced commissioning time. This translates to lower engineering costs and faster time-to-production for new lines and retrofits. Application: transformer protection in plants with mixed voltage zones and modular substations. Feature → Business Impact → Application: 8 digital inputs, 9 digital outputs, plus 2 analog inputs and 2 analog outputs provide rich I/O for protection logic, metering, and signaling, improving fault detection accuracy and reducing false trips. Application: integrated protection schemes for transformer banks and switchgear panels. Feature → Business Impact → Application: Profibus-DP over fiber optic ST delivers robust, noise-immune communication between the relay and PLCs or SCADA, lowering diagnostic time and enabling seamless remote monitoring. Application: scalable integration in centralized monitoring architectures. Feature → Business Impact → Application: Base relay compatibility (ETR-4000) and Trip Coil Monitor with IRIG-B and Sensitive Ground Input support offer upgrade paths and enhanced protection coordination, reducing downtime during maintenance windows. Application: upgrade projects and complex protection schemes. Feature → Business Impact → Application: Removable terminals and semi-flush mounting simplify installation and field servicing, cutting wiring errors and deployment time. Application: retrofit work in dense panel environments. Feature → Business Impact → Application: Zone selective interlocking (2) and high-current sensing options (5A, 1A) improve selective tripping performance, decreasing arc flash exposure and improving personnel safety. Application: utility-scale and industrial transformers with stringent fault isolation requirements.
