FAQs
For successful field deployment, plan removable terminals and semi-flush mounting to simplify terminal access and servicing. The unit is compatible with the ETR-4000 base relay, supports 8 digital inputs, 9 outputs, and dual analog IO, and uses a wide power supply range (19-300 Vdc, 40-250 Vac). Ensure proper fiber optic networking for Mbus TCP or DNP3 TCP/UDP over LC duplex FO Enet and provide adequate clearance for heat dissipation and access to diagnostics.
The relay combines 2 analog inputs/outputs and 2 current sensing inputs with 8 digital inputs and 9 digital outputs to implement layered protection logic: voltage, current, metering, and differential protection as part of transformer protection schemes. With 50/60 Hz operation and wide power ranges, it supports coordinated protection across devices, reducing misoperations and enabling faster fault isolation in substations or industrial facilities.
Yes. It supports Mbus TCP and DNP3 TCP/UDP communications over LC duplex fiber Ethernet, enabling secure remote monitoring and integration with SCADA or MES systems. The I/O and Modbus/DNP3 capabilities allow easy integration into existing protection architectures, while URTD interface options and IRIG-B input support enhanced trip coordination and time synchronization in complex power networks.
Compliance details for this model are provided by Eaton and can vary by configuration. The product page notes Compliances as Contact Manufacturer, so verify CE marking, SIL levels, and IP ratings with Eaton for your installation and regulatory context. Having formal confirmations ensures proper safety, interoperability, and warranty enforcement in your jurisdiction.
ROI benefits come from reduced protection misoperations, fewer field devices due to consolidated analog and digital IO, and streamlined maintenance thanks to removable terminals and straightforward semi-flush installation. The unit supports remote monitoring via Mbus/DNP3 over Ethernet, enabling early fault detection and proactive maintenance. A one-year warranty (or 18 months from shipment) provides initial risk mitigation during the critical deployment phase.
