FAQs

The ETR-4000-2A2LB1 supports eight digital inputs, nine outputs, and communications via Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet, enabling straightforward integration with modern SCADA. Its removable terminals and projection mounting simplify field retrofits, while the broad power range supports diverse site power architectures. This compatibility minimizes integration risk and reduces commissioning time.
Key specs include a power supply range of 19-300Vdc and 40-250Vac, operating at 50/60 Hz, plus two current-sensing inputs for differential protection and metering. With eight inputs and nine outputs, the relay can run complex protection schemes, deliver accurate metering, and provide timely alarms, which improves fault isolation and energy management across transformer assets.
Yes, the device employs conformal coating on circuit boards to resist moisture and corrosion, and it uses removable terminals to ease maintenance. While the data sheet notes Compliances as manufacturer-directed, the included warranty and Eaton’s established protection relay lineage indicate strong reliability for industrial applications, especially when installed with proper enclosure and routing.
The relay uses Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet, enabling secure, high-speed data transfer to SCADA, historians, or predictive maintenance platforms. This supports remote fault diagnostics, event logging, and time-stamped measurements, reducing onsite visits and improving overall system visibility.
Warranty follows Eaton policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. For technical support, consult the Eaton specification sheet and partner resources, which provide installation guidelines, spare parts, and service options to maximize uptime and return on investment.
