Quick Summary

The Eaton transformer relay protects transformers and nearby equipment in industrial power systems, enabling precise tripping, monitoring, and diagnostics. Operators often face nuisance trips and downtime when monitoring multiple protection functions across feeders, motors, and switchgear, which eats into uptime and maintenance efficiency. The datasheet does not specify CE, SIL, or IP certifications; confirm with Eaton to ensure regulatory alignment for your installation. Integrated Modbus TCP and DNP3 communications over Ethernet simplify remote monitoring, while removable terminals and 8 inputs and 9 outputs support scalable protection configurations. In practice, this device can reduce engineering effort, improve diagnostic visibility, and help meet uptime targets for critical power networks.

FAQs

Begin with power and protocol readiness: verify the 19-300 Vdc or 40-250 Vac supply, confirm 50/60 Hz operation, and plan the 8 digital inputs with 9 digital outputs. Mount the unit semi-flush, connect removable terminals, and enable Modbus TCP or DNP3 over Ethernet RJ-45. Program protection logic for transformer differential, power protection, and metering as required. The result is a scalable, maintainable protection layer that minimizes wiring errors and simplifies future upgrades.
Key features include 2 current-sensing inputs, 8 digital inputs, 9 digital outputs, and Modbus TCP/DNP3 communication. These enable robust protection schemes, precise fault detection, and remote diagnostics. The device supports multiple protection and metering functions across 50/60 Hz systems, with removable terminals for quick field servicing, contributing to lower downtime and faster fault isolation.
Yes. With a transformer protection focus, 8/9 I/O, modular interfaces, and Ethernet-based communications, it serves both substation environments and OEM equipment. The IRIG-B Trip Coil Monitor and URTD interface add time synchronization and monitoring options, while semi-flush mounting and conformal coating support rugged, ruggedized deployments typical of substations and industrial facilities.
The datasheet does not list explicit CE, SIL, or IP certifications. For regulatory compliance, consult Eaton to confirm exact certifications for your region and application. When deploying in regulated environments, verify compatibility with local electrical codes and industry standards, and document compliance through Eaton’s official certification guidance before commissioning.
ROI benefits come from reduced downtime, fewer nuisance trips, and easier maintenance enabled by remote Ethernet monitoring and diagnostics. The device’s modular I/O, removable terminals, and wide power range simplify installation and future upgrades, while the integrated protection and metering reduce engineering hours. A one-year warranty and the option for extended support further lower long-term ownership costs.
