Quick Summary

Eaton transformer relay ETR-4000-2A0DB0 protects transformers in power systems. This solution targets the common pain point of slow fault isolation and protection miscoordination that can extend downtime. It combines robust protection features with modular I/O for easy scalability. While regulatory certifications vary by region, typical buyers look for CE marking and SIL readiness, with enclosure and safety approvals confirmed by the manufacturer. The unit supports 19-300 Vdc and 40-250 Vac, 50/60 Hz operation, eight digital inputs, nine outputs, and Profibus-DP over fiber for reliable field communication. This translates to faster diagnostics, reduced maintenance windows, and a scalable platform for transformer protection, metering, and zone-selective interlocking in industrial plants.

Eight digital inputs and nine outputs provide a complete protective logic interface in a compact panel. This feature enables richer signals for faster fault recognition and simpler wiring, reducing panel complexity and installation time. It is ideal for transformer protection schemes requiring local monitoring, metering, and control within a single relay. The wide power supply range of 19-300 Vdc and 40-250 Vac, with 50/60 Hz operation, offers broad compatibility with existing plant power architectures and reduces the need for extra adapters, delivering improved reliability in mixed-voltage environments. Profibus-DP communication over fiber optic ST delivers noise-immune, long-reach fieldbus networking, enabling centralized protection logic and easier diagnostics across distributed transformer assets, even in electrically noisy environments. This supports scalable protection architectures and faster fault isolation across multiple devices. Removable terminals and a semi-flush mounting style simplify on-site wiring, maintenance, and future upgrades, while conformal-coated circuit boards provide enhanced durability in harsh industrial settings. The device supports I/O options such as Trip Coil Monitor, IRIG-B, and URTD interfaces, expanding compatibility with existing protection schemes and time synchronization needs. Sensing inputs enable Differential Protection, Current Protection, and Metering, delivering precise fault detection and accurate electrical measurements essential for reliable transformer protection. Zone Selective Interlocking with a 2-zone configuration accelerates selective relay action to minimize system-wide outages, improving overall plant availability. With the ETR-4000-2A0DB0, installation and service are streamlined, reducing downtime and enabling faster, data-driven maintenance decisions.

FAQs

Begin by verifying supply voltage compatibility (19-300 Vdc, 40-250 Vac) and confirming the Profibus-DP fiber optic connection. Mount the unit on a semi-flush panel and attach the removable terminals for DI/D0 wiring. Use the 8 digital inputs and 9 outputs to integrate protection logic, metering, and alarms. Ensure proper grounding, configure the network address, and test signaling with a controlled fault to validate zone selective interlocking operation.
Key specs include eight digital inputs, nine digital outputs, two current sensing inputs, and phase current ratings of 5A and 1A. The device operates on 50/60 Hz and accepts a wide power range of 19-300 Vdc or 40-250 Vac. It supports differential protection, current protection, and metering, making it suitable for transformer protection schemes and real-time monitoring.
Yes. The ETR-4000-2A0DB0 is designed as a transformer protection relay with rich I/O, differential and current protection capabilities, and metering. Its Profibus-DP over fiber optic interface supports reliable communication in electrically noisy environments, while its removable terminals and conformal coating simplify installation and maintenance in harsh industrial settings.
Compliance details vary by region and installation. The product datasheet notes that compliances should be confirmed with the manufacturer. In practice, buyers typically verify CE marking, safety approvals, and SIL readiness with Eaton or their authorized distributor to ensure regional regulatory alignment and installation certifications.
The relay’s removable terminals and modular I/O reduce field wiring time and simplify upgrades, lowering maintenance costs. Its integrated metering and diagnostic capabilities support faster fault localization, reducing downtime. Zone selective interlocking minimizes system outages by enabling targeted tripping, contributing to improved uptime and overall return on investment for transformer protection schemes.
