Quick Summary

Eaton transformer relay delivers robust transformer protection and monitoring for industrial power networks. Engineers often struggle with integrating protective relays into existing control schemes, diagnosing faults quickly, and coordinating trips across multiple devices. Certification details should be confirmed with the manufacturer; when available, CE compliance, IP ratings, and SIL support are common in this class. The device supports Modbus TCP or DNP3 TCP/UDP over Ethernet RJ-45 for seamless data exchange, and its eight digital inputs plus nine outputs provide scalable protection logic for transformer assets in diversified installations.

FAQs

The ETR-4000-2A0CA0 is designed with removable terminals and a semi-flush mounting method, facilitating straightforward field wiring and service. Plan for eight digital inputs and nine outputs, ensure proper copper conduc tors are used, and verify mounting clearance for the 8.7 in height and 9.72 in width specifications. Compatibility with URTD, IRIG-B, and Trip Coil Monitor options should be verified during installation planning.
Key specs include eight digital inputs, nine digital outputs, two current sensing inputs, 50/60 Hz operation, and a power supply range of 19-300 VDC or 40-250 VAC. It supports Modbus TCP or DNP3 TCP/UDP over Ethernet RJ-45, with differential protection, current protection, metering capabilities, and Zone Selective Interlocking (2). These features enable precise transformer protection and diagnostics.
Yes. The ETR-4000-2A0CA0 uses Modbus TCP or DNP3 TCP/UDP over Ethernet RJ-45 for field communication, enabling integration with modern SCADA, MES, and protection systems. This compatibility supports remote monitoring, event logging, and centralized control, reducing on-site maintenance and speeding fault isolation across transformer fleets.
The unit includes Zone Selective Interlocking (2) and offers Trip Coil Monitor and IRIG-B interface options. This combination enables precise trip coordination across transformer banks and accurate time-stamping for event logs, improving selectivity and reducing the risk of unnecessary outages in complex substation configurations.
