Eight inputs and nine outputs provide comprehensive protection logic at the device level, enabling precise tripping schemes and metering. This translates to faster fault discrimination and reduced nuisance trips in transformers and feeder circuits, especially in substations and industrial plants that require clear I/O mapping and quick diagnostics. The unit supports a wide power supply range of 19-300 Vdc and 40-250 Vac, simplifying integration with existing control systems and reducing stocking variety. Communication is flexible with Modbus RTU or DNP3 RTU over RS-485, enabling seamless integration with modern SCADA and protection schemes, which improves remote monitoring, fault analytics, and maintenance planning. I/O versatility includes Trip Coil Monitor, IRIG-B, Sensitive Ground Input, and URTD Interface, expanding synchronization, signaling, and trip verification for critical loads. Removable terminals and projection mounting streamline installation and field service, lowering commissioning time and wiring errors. Zone Selective Interlocking (ZSI) at level 2 supports fast, selective fault clearance, minimizing outage impact and improving grid stability in distributed transformer networks. This relay is designed for rugged industrial environments and offers compatibility with common protection schemes, supporting a modular approach to asset protection and lifecycle cost reduction.

FAQs

Begin by ensuring compatible power supply within 19-300 Vdc or 40-250 Vac. Use the removable terminals for clean pre-wiring, then mount via projection method for secure alignment. Connect Modbus RTU or DNP3 RTU over RS-485 to your SCADA network, and map the eight digital inputs and nine outputs to your protection logic. Verify wiring with the Eaton datasheet and perform a staged commissioning to minimize system downtime.
Yes. The unit is designed to operate with Modbus RTU or DNP3 RTU over D-Sub RS-485, enabling integration with diverse protection schemes. This flexibility simplifies SCADA integration, supports remote diagnostics, and reduces field visits by centralizing monitoring and event reporting within your existing control architecture.
Its 8 inputs and 9 outputs support complex protection logic, along with current sensing inputs and zone selective interlocking (ZSI) for selective fault clearance. The device handles 50/60 Hz operation and accepts a broad power supply range, which simplifies retrofits and upgrades in substations. The integration with RS-485 protocols allows seamless data exchange with protection relays and SCADA systems, enhancing reliability and response times.
Compliances are specified as Contact Manufacturer in the product data. For exact certifications such as CE marking, IP ratings, or SIL readiness, consult the ETR-4000-2A1GA1 datasheet or contact Eaton support to confirm model-specific approvals and any regional requirements prior to procurement.
Expect reduced downtime through faster fault isolation and improved fault visibility via remote diagnostics. The 8/9 I/O configuration supports precise protection schemes, while RS-485 communication streamlines SCADA integration, reducing commissioning time and field service visits.
