Quick Summary

The Eaton transformer relay ETR-4000-2A0FB1 is a transformer protection relay that monitors and protects transformers in power systems. But engineers often wrestle with integrating protection relays into modern control schemes and ensuring reliable communications. Certification details are available from Eaton on request; typical deployments require CE and regional safety compliance where applicable. This solution pairs Modbus RTU or DNP3 RTU over fiber with 8 digital inputs, 9 digital outputs, 2 current sensing inputs, and a 19-300 Vdc / 40-250 Vac power range to support scalable diagnostics. These capabilities translate into faster fault isolation, lower mean time to repair, and safer, more reliable transformer operation.

Eight digital inputs and nine digital outputs enable comprehensive protection logic and remote signaling, reducing wiring complexity and speeding commissioning in power distribution panels. The business impact is clearer fault detection and faster automated responses to upstream faults, making it ideal for substation retrofits and OEM equipment where space and labor are at a premium. The 2 current sensing inputs and configurable phase current options (5A/1A) provide precise sensing for differential protection and metering, translating to improved accuracy and reduced nuisance trips in industrial plants. Power supply flexibility, supporting 19-300Vdc and 40-250Vac with 50/60 Hz operation, allows seamless integration with existing plant power architectures, cutting procurement and inventory costs. The removable terminals and projection mounting simplify field installation and maintenance, reducing downtime during upgrades. Conformal coated circuit boards enhance reliability in harsh environments, while Modbus RTU or DNP3 RTU communications over fiber optic ST ensure robust, secure remote monitoring. The I/O options—Trip Coil Monitor, IRIG-B, and URTD Interface—extend compatibility with legacy protection schemes and timing synchronization, enabling easier integration with modern SCADA and EMS systems. These features support measurable outcomes, including improved reliability, faster diagnostics, and a lower total cost of ownership for transformer protection relays in utilities and manufacturing facilities.
