Eaton ETR-5000-2A1EA1 Transformer Relay - Profibus-DP
Part Number: ETR-5000-2A1EA1
Quick Summary
Eaton transformer relay ETR-5000-2A1EA1 protects transformers by monitoring conditions and triggering selective isolation in industrial power systems. Engineers often face downtime from transformer faults and the challenge of integrating protection relays into existing Profibus-DP networks. Certification specifics (such as CE, SIL, or IP ratings) are provided by the manufacturer and must be confirmed before purchase. This device offers robust transformer protection capabilities with Profibus-DP compatibility and flexible power options, delivering reliable operation in manufacturing plants, substations, and data centers while supporting modern automation architectures. Its 8 digital inputs and 9 outputs support complex protection logic without external multiplexers, reducing wiring and commissioning time. With Eaton’s support, it’s a practical choice for compliance-driven projects and long-term asset management.

Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: Eight digital inputs and nine outputs, plus two current sensing inputs, provide a compact yet capable protection platform that reduces the need for external relays, lowers wiring complexity, and speeds configuration. This supports transformer protection schemes in substations and plant switchgear, delivering measurable reductions in wiring costs and fault response times. Feature → Business Impact → Application: Profibus-DP over D-SUB / RS-485 enables seamless integration with plant networks, remote monitoring, and coordinated protection across automation architectures. Users gain centralized visibility, faster fault location, and easier commissioning in factory automation and data centers. Feature → Business Impact → Application: A broad power-supply range of 19–300 VDC and 40–250 VAC supports mixed-voltage environments, reducing inventory and enabling field deployments without multiple Power supply subsystems. Application: installations in mixed-voltage facilities. Feature → Business Impact → Application: Sensing inputs cover Current, Voltage, Power, and Differential protection for precise fault discrimination and metering, improving selectivity and reducing unintended outages in transformer protection schemes. Feature → Business Impact → Application: I/O options such as Trip Coil Monitor, Sensitive Ground Input, IRIG-B URTD Interface, and Zone Selective Interlocking (2) enhance timing, signaling, and coordination, enabling advanced protection schemes and faster isolation in critical applications. Feature → Business Impact → Application: Removable terminals and Projection mounting simplify installation, maintenance, and field retrofits, particularly when upgrading from an ETR-4000 base relay, reducing downtime and lifecycle costs. Warranty and support: A one-year warranty from installation (or eighteen months from shipment) provides risk mitigation and access to Eaton’s technical resources for ongoing reliability in industrial environments.

FAQs
Yes. The unit uses Profibus-DP over D-SUB / RS-485 for networked protection and is designed to work with Eaton's transformer protection relay family, including upgrade paths from the ETR-4000 base relay. Its eight digital inputs, nine digital outputs, and two current sensing inputs support integrated protection logic without requiring extensive external interfaces, simplifying retrofits and commissioning.
The ETR-5000-2A1EA1 supports current, voltage, power, and differential protection sensing inputs, along with metering capabilities for transformer protection schemes. It also offers zone selective interlocking (2) to improve selectivity and minimize outage impact, and supports various I/O options to tailor protection to specific transformer configurations and fault scenarios.
The relay accepts 19–300 VDC or 40–250 VAC with a 50/60 Hz frequency rating, enabling operation from diverse plant power sources. Installers will appreciate removable terminals and projection mounting for easy wiring and maintenance. The device is compatible with industry-standard transformer protection layouts and can be integrated into control panels or switchgear without extensive re-wiring.
Key resources include the Eaton Specification Sheet for the ETR-5000-2A1EA1, plus brochures on E-Series protective relays and multiple programming videos.
