Quick Summary

ETR-4000-2A1DA1 transformer relay provides comprehensive transformer protection and monitoring for industrial power systems. Engineers often struggle with reliable fault detection, fast trip coordination, and networked reporting in compact control panels. Compliance details should be confirmed with the manufacturer; public CE or SIL listings are not shown in the data, so verification is recommended. With Profibus-DP over fiber, eight digital inputs and nine outputs, and a wide power-supply range of 19-300 Vdc or 40-250 Vac, it scales from small to large transformer protection in plants, data centers, and utilities. This combination supports reduced downtime, improved operability, and easier integration with existing control architectures.

FAQs

Installing the ETR-4000-2A1DA1 involves mounting the unit in a suitable panel with its projection mounting method and connecting the eight digital inputs and nine outputs to the transformer protection scheme. The terminals are removable for easier wiring, and the device seamlessly wires into existing Profibus-DP networks via fiber optic ST. Proper torque, cabling separation, and conformity to the Eaton installation guidelines ensure reliable operation and faster commissioning.
This relay supports current protection and metering, differential protection, and zone selective interlocking (two zones). It also offers Trip Coil Monitor and IRIG-B time synchronization, enabling accurate trip coordination and diagnostics. These features together reduce misoperations, accelerate fault isolation, and improve overall transformer reliability in challenging industrial environments.
Yes. The unit supports Profibus-DP over fiber optic ST, delivering reliable, EMI-resistant communication suitable for harsh plant conditions. This compatibility enhances remote monitoring, integration with SCADA, and easier distribution of protection logic across multi-bay transformer setups without sacrificing signal integrity.
The data provided lists Compliances as Contact Manufacturer, indicating that specific certifications (such as CE or SIL) should be confirmed directly with Eaton for your installation and regulatory requirements. Always verify with the manufacturer to ensure the product meets your local standards and approval processes prior to purchase or deployment.
The ETR-4000-2A1DA1 can lower total cost of ownership through reduced wiring complexity, faster commissioning, improved fault isolation, and fewer false trips thanks to precision current sensing and differential protection.
