FAQs

Installation begins by mounting the unit with its semi-flush method and securing removable terminals for quick wiring. Connect power to the 19-300 Vdc / 40-250 Vac range, wire the 8 digital inputs and 9 digital outputs, and integrate RS-485 Modbus or Ethernet TCP for SCADA communication. Follow the commissioning procedure in the Eaton documentation and verify URTD/IRIG-B options as needed for time synchronization and trip-coil monitoring.
It combines a base ETR-4000 relay with 2 current sensing inputs, 8 digital inputs, 9 outputs, and multiple protection and metering capabilities. The unit supports Zone Selective Interlocking and Trip Coil Monitor, enabling fast fault isolation and coordinated protection across transformer banks while allowing remote monitoring via RS-485 and Ethernet.
Yes. The relay provides Modbus/ DNP3 RTU over RS-485 and Modbus/ DNP3 TCP over Ethernet RJ-45, enabling straightforward data exchange with most SCADA/DCS platforms. Ensure proper addressing, baud rate, and network security settings, and validate that the system supports the required protocol version for reliable supervision.
Certification details are managed by Eaton and should be confirmed with the manufacturer. Typical considerations include CE markings and appropriate IP/SIL classifications depending on the installation. Always reference Eaton's official documentation or contact Eaton support to confirm the exact certifications for your region and application.
ROI is driven by reduced downtime from faster fault isolation, fewer spurious trips, and lower maintenance costs due to remote diagnostics and modular I/O. The unit’s universal power range, ease of installation, and compatibility with existing RS-485/Ethernet networks shorten commissioning time and improve protection reliability, leading to lower lifecycle costs in transformer-heavy facilities.
