Eaton ETR-5000-2B0EA1 Transformer Relay - Profibus-DP

Power supply range and mechanical design enable global deployment. The ETR-5000-2B0EA1 accepts 19-300 Vdc or 40-250 Vac and operates at 50/60 Hz, with removable terminals and a projection mounting method for fast, secure installation. Business impact: reduced wiring errors, faster panel builds, and easier retrofits in legacy equipment. Application: transformer protection in substations, switchgear, and machine rooms where dual‑voltage operation simplifies sourcing and maintenance. I/O and communications expand protection logic. With 8 digital inputs, 9 outputs, 2 analog inputs, 2 analog outputs, and 2 current-sensing inputs, the relay supports complex protection schemes and metering. It also provides Profibus-DP over D-Sub/RS-485 and compatibility with the ETR-4000 base relay. Business impact: flexible signaling, precise trip coordination, and seamless integration into automation networks. Application: transformer bank protection and remote monitoring in automation architectures. Protection capabilities deliver reliable fault detection. Sensing inputs cover current protection, metering, differential protection, and voltage protection, while zone selective interlocking (2) enables fast selective trips. I/O options include Trip Coil Monitor URTD and IRIG-B, enabling precise timing and monitoring. Business impact: improved fault isolation, reduced outage duration, and compliance with protective coordination standards. Application: transformer protection in power distribution and critical facilities. Installation and lifecycle management are simplified. The unit features removable terminals, a projection mounting style, and a compatible base relay (ETR-4000), enabling easy upgrades and retrofit projects. Warranty terms specify one year from installation or 18 months from shipment, whichever occurs first, and 'Compliances: Contact Manufacturer' indicates that certification details should be verified with Eaton. Business impact: lower maintenance overhead and faster time-to-value. Operational insights and long-term value. With current protection and metering capabilities, along with robust communication options, the ETR-5000-2B0EA1 supports monitoring dashboards, alarm management, and predictive maintenance programs. Industry context: transformer protection relays are essential for uptime in data centers, manufacturing, and energy infrastructure. The combination of I/O density, flexible communication, and modular compatibility helps drive ROI through reduced downtime, optimized asset protection, and streamlined serviceability.
