FAQs
Begin by verifying the 8 digital inputs and 9 outputs align with your protective logic and trip schemes. Use the removable terminals for straightforward wiring, and configure the Vdc/Vac power inputs to match your plant supply (19-300 Vdc or 40-250 Vac). Connect Modbus or DNP3 TCP/UDP over LC fiber Ethernet for SCADA integration, and reference the ETR-4000 base relay if upgrading a legacy system.
The device supports 19-300 Vdc and 40-250 Vac power ranges, operates at 50/60 Hz, and includes 2 current sensing inputs along with 8 DI and 9 DO channels. It is designed for differential, power protection, and metering tasks and can interwork with Mbus TCP or DNP3 TCP/UDP communications for remote data and alarms.
Yes. With Zone Selective Interlocking configured across its 8 inputs and 9 outputs, the relay provides selective tripping logic to minimize outage impact. This is particularly valuable in substations or multi-transformer feeders where selective clearance improves system availability and reduces fault energy.
Compliances are listed as to be confirmed with the manufacturer. For safe deployment, verify CE, SIL, and IP-related certifications appropriate to your region and enclosure environment. Always confirm the exact approvals for your installation with Eaton to ensure regulatory alignment and warranty validity.
Remote monitoring via Mbus TCP or DNP3 reduces site visits, enabling proactive diagnostics and faster fault resolution. The flexible power inputs, rugged construction, and conformal coating improve field reliability, lowering maintenance costs. ROI comes from reduced downtime, streamlined protection coordination, and easier migration from older protection relays.
