Eaton Specification Sheet - ETR-5000-2A1LA0
8 digital inputs and 9 digital outputs provide flexible protection logic and remote signaling capabilities, while 2 current-sensing inputs support accurate transformer protection and metering. This combination reduces wiring complexity and enables precise zone-interlocking, improving system reliability and enabling faster fault isolation in substations. The device supports a wide power-supply window of 19-300 Vdc and 40-250 Vac with a 50/60 Hz frequency rating, which minimizes site transformers or power conditioning steps and streamlines installations across mixed-power environments. Communication is enabled via Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet, enabling seamless SCADA integration and remote diagnostics, which lowers field service costs and improves asset visibility. Removable terminals and semi-flush mounting simplify installation, testing, and future upgrades, while compatibility with the ETR-4000 base ensures scalable, modular protection architecture for transformer protection relays. Additional I/O options include IRIG-B, URTD interface, Trip Coil Monitor, and Sensitive Ground Input, expanding protection coverage and monitoring with minimal footprint in control rooms or switchgear cabinets.

FAQs
The device uses removable terminals and a semi-flush mounting method, and is designed to work with the ETR-4000 base. Plan for 8 digital inputs and 9 outputs, wire the 2 current sensing inputs for protective logic, and ensure the LC duplex fiber Ethernet link for Mbus TCP or DNP3 TCP/UDP. This simplifies retrofits and minimizes downtime during integration.
Key specs include 19-300 Vdc and 40-250 Vac power supplies with a 50/60 Hz rating, 8 inputs and 9 outputs, 2 current sensing inputs, and support for Mbus TCP or DNP3 TCP/UDP over LC duplex fiber. It also features a base relay (ETR-4000) compatibility and a 5 A / 1 A phase current range for protection schemes.
Yes. It supports Mbus TCP or DNP3 TCP/UDP over LC duplex fiber optic Ethernet, enabling reliable remote monitoring and SCADA integration across plant networks, with reduced risk of interference and improved data integrity.
Compliances are managed by the manufacturer. Confirm regional certifications such as CE, SIL readiness, and applicable IP ratings with Eaton or your Eaton distributor to ensure alignment with your installation site requirements.
The product is covered by Eaton’s standard warranty policy, typically one year from installation or eighteen months from shipment, whichever occurs first. For service or extended coverage, contact Eaton support to discuss upgrade options, spare parts, and equipment refurbishment.
