FAQs

Follow Eaton's installation guidance for projection mounting and removable terminals. Power the unit from 19-300 VDC or 40-250 VAC, connect 8 digital inputs and 9 digital outputs, and link Modbus TCP over Ethernet RJ45 to your SCADA system. Use shielded CAT5e/6 cables and proper grounding to minimize electrical noise and ensure reliable communication.
The relay supports voltage protection and metering, differential protection, current protection and metering, and power protection and metering, with 2 current sensing inputs and 8 DI / 9 DO for alarms and trips. This enables precise fault detection, energy monitoring, and coordinated protection within transformer protection schemes.
Compliance specifics are defined by Eaton; contact the manufacturer for exact certifications such as CE, SIL readiness, or IP ratings. The device is designed for transformer protection in industrial networks and supports standard network protocols for reliable integration and reporting.
Ethernet connectivity via Modbus TCP or DNP3 TCP/UDP over RJ45 enables real-time monitoring, remote configuration, and integration with SCADA/MES systems. This reduces on-site visits, speeds fault localization, and supports zone selective interlocking for faster, targeted tripping and reduced outage impact.
Opt for projection mounting with removable terminals to simplify retrofits, plan for 50/60 Hz operation, and map I/O efficiently (8 DI, 9 DO) to shorten commissioning time and lower ongoing maintenance costs, delivering a faster return on investment over the relay’s lifecycle.
