Eaton ETR-5000-2A0FB1 Transformer Relay - Modbus RTU

Feature → Business Impact → Application: Communication interfaces enable Modbus RTU or DNP3 RTU communications over fiber optic ST, delivering secure, low-latency data to SCADA and protection systems; Benefit: enhanced remote monitoring, reduced commissioning time, and improved data integrity for transformer protection schemes in substations. Application: interconnect with power management software and remote diagnostics to support predictive maintenance. Feature → Business Impact → Application: Eight digital inputs and nine digital outputs provide flexible I/O for protection logic, metering, and interlocks; Benefit: streamlined protection logic, simplified wiring, and faster fault isolation. Application: use alongside Zone Selective Interlocking (2) to coordinate fault clearance across feeders with minimal downstream disruption. Feature → Business Impact → Application: Wide power-supply range (19-300 Vdc, 40-250 Vac) and 50/60 Hz compatibility simplify installation across diverse plant environments; Benefit: reduced inventory and faster deployment. Application: plug-and-play in retrofit projects or new builds for transformer protection without custom power supplies. Feature → Business Impact → Application: IRIG-B time synchronization, URTD interface, and Trip Coil Monitor enhance time accuracy, remote trip verification, and coil fault detection; Benefit: higher protection accuracy, faster event reconstruction, and lower risk of miscoordination. Application: mission-critical substations and industrial plants needing precise protection timing. Feature → Business Impact → Application: Conformal coated circuit boards and removable terminals provide rugged reliability in harsh environments; Benefit: extended service life and easier field maintenance. Application: offshore, chemical, or dusty plant areas where environmental resistance matters. Feature → Business Impact → Application: Compatibility with base relay ETR-4000 and 8/9 I/O configuration supports scalable protection architectures; Benefit: reuse of existing protection strategies and simplified upgrade paths. Application: phased modernization programs in large electrical networks. Feature → Business Impact → Application: Modbus/DNP3 RTU over fiber supports secure, redundant communication paths; Benefit: resilience against interference and cyber threats; Application: critical process installations requiring robust data channels.
