Eaton ETR-4000-2A1DB1 Transformer Relay - Profibus-DP over Fiber Optic ST
Part Number: ETR-4000-2A1DB1
Quick Summary
Eaton transformer relay protects transformers in industrial electrical networks, delivering fast fault detection, selective tripping, and coordinated protection for critical equipment. Maintenance teams struggle with nuisance trips, mis-set protection, and hidden failures that cause unplanned downtime and expensive service calls. In this space, CE compliance, SIL reliability targets, and rugged IP-rated enclosures influence safety, uptime, and maintenance cost in harsh plant environments. With Profibus-DP communication over fiber, removable terminals, and a compact projection-mount design, it simplifies installation and long-term maintenance while lowering total cost of ownership. This makes it suitable for transformer protection in manufacturing plants, data centers, and energy facilities.

FAQs
Begin by wiring the 8 digital inputs and 9 digital outputs to your control network, then configure the Profibus-DP interface over the ST fiber optic link. Ensure the device power supply is within 19-300 Vdc or 40-250 Vac, and align the zone selective interlocking settings for coordinated protection with the PLC or DCS. This setup minimizes wiring complexity while ensuring reliable communication and quick fault isolation.
Key specs include 8 digital inputs, 9 digital outputs, 2 current sensing inputs (5A and 1A phase current options), power supply range of 19-300 Vdc or 40-250 Vac, and a 50/60 Hz frequency rating. It uses Profibus-DP over fiber optic ST for communication, with a projection mounting and removable terminals for easy field service and wiring changes.
Yes. Designed as a transformer protection relay, it supports differential protection, current sensing, and zone selective interlocking, enabling fast fault detection and selective tripping. Its rugged construction with conformal coating and fiber-backed Profibus-DP communication ensures reliable operation in harsh industrial environments and integrations with modern control systems.
Plan for projection mounting with removable terminals to simplify wiring and field maintenance. Ensure conformal-coated PCB assemblies for environmental durability, and prepare Profibus-DP over fiber connections for robust communications. Consider an URTD interface option for extended I/O flexibility and ensure grounding and shielding meet plant safety standards to minimize EMI effects.
