Quick Summary

Eaton transformer relay protects transformers in power distribution and industrial automation. Engineers face downtime and slow fault isolation when protection schemes fail to communicate essential status and diagnostics. Industry-standard protections commonly include CE marking, SIL-ready capability, and rugged IP-rated enclosures to ensure reliability in harsh environments. With Modbus TCP or DNP3 over Ethernet RJ45 and removable terminals, this relay enables fast integration and proactive maintenance. Its wide power range and 8 inputs / 9 outputs, plus compatibility with the ETR-4000 base, translates to lower installation cost and easier commissioning. Perfect for OEMs and service providers.

Wide power supply range and 50/60 Hz compatibility enable global deployments with a single unit. This reduces spare parts and simplifies procurement across regional sites while easing stocking and training. Ideal for substations, data centers, and OEM equipment where both DC and AC sources must be monitored. Eight digital inputs and nine digital outputs with removable terminals streamline wiring and maintenance. This arrangement supports faster commissioning, easier field upgrades, and reduced risk of loose connections, enabling reliable signaling and actuator control across protection zones. I/O options such as Trip Coil Monitor, URTD Interface, and IRIG-B provide extended diagnostics and timing coordination. This enhances anomaly detection, time synchronization, and compatibility with mission-critical protection architectures in utility substations and industrial installations. Modbus TCP or DNP3 TCP/UDP over Ethernet RJ45 enables remote SCADA integration. The result is centralized monitoring that reduces on-site visits and accelerates fault diagnosis for OEMs and utilities. Phase current options of 5A and 1A, plus two current-sensing inputs, support accurate protection setpoints across transformer ratings. This translates to precise fault signaling and reduced nuisance trips in distribution networks. Removable terminals and semi-flush mounting further simplify installation and serviceability, delivering faster time-to-value for engineering teams.

FAQs

Begin by confirming the unit’s power supply range and mounting requirements. Connect the eight digital inputs and nine digital outputs through the removable terminals according to your protection scheme. Use the Modbus TCP or DNP3 over Ethernet RJ45 interface for SCADA integration, then configure trip setpoints and diagnostic logging with Eaton’s configuration tools. Ensure proper grounding and enclosure integrity to maintain signal quality.
Key specs include a power supply range of 19-300 VDC and 40-250 VAC, with a 50/60 Hz frequency rating. It features two current sensing inputs, phase currents of 5A and 1A, eight digital inputs, and nine digital outputs. Communication is via Modbus TCP or DNP3 TCP/UDP over Ethernet RJ45. Terminals are removable, supporting reliable field installation and maintenance.
Substations and utility-scale transformer protection are primary applications, along with OEM equipment and data centers requiring reliable transformer monitoring. The device’s wide power range, remote communication options, and flexible I/O enable integration into existing protection architectures and SCADA systems, reducing downtime, improving fault clarity, and supporting time-critical protection schemes.
Current product data indicates ‘Compliances: Contact Manufacturer,’ so consult the Eaton specification sheet for definitive regulatory details. In practice, transformer protection relays used in critical infrastructure typically address CE marking, SIL readiness, and rugged enclosure standards. Always verify with Eaton’s datasheets and regional certifications to ensure compliance for your installation site.
Remote monitoring via Modbus TCP/DNP3 reduces field visits by enabling centralized diagnostics and proactive maintenance. The unit’s removable terminals simplify serviceability, while compatibility with the ETR-4000 base supports scalable upgrades without complete system rewrites. Expect lower downtime, faster fault resolution, and a shorter time-to-value for transformer protection initiatives.
