FAQs

Plan for projection mounting with removable terminals to simplify field wiring. Verify compatible power supply within 19-300 Vdc or 40-250 Vac and ensure fiber Ethernet connectivity via Mbus TCP or DNP3 TCP/UDP. Prepare for environmental conditions by inspecting conformal-coated circuit boards and protective enclosures to maximize reliability in harsh industrial settings.
The unit supports Mbus TCP or DNP3 TCP/UDP communications over LC duplex fiber Ethernet, enabling seamless SCADA integration and remote diagnostics. Plan for network addressing, protocol mapping, and QoS to maintain deterministic communication, while leveraging its 8 DI / 9 DO I/O to implement clear protection logic signals.
Yes. The transformer relay is designed for a dual power range of 19-300 Vdc and 40-250 Vac with a 50/60 Hz frequency rating, enabling operation across diverse regions and applications without multiple SKUs. This flexibility reduces stocking complexity and simplifies field commissioning.
ETR-5000-2A3LB1 offers 8 digital inputs and 9 digital outputs, 2 current sensing inputs, and zone-selective interlocking with 2 zones. It supports IRIG-B, Trip Coil Monitor, URTD interface, and Sensitive Ground Input. These features enable comprehensive transformer protection, fast fault clearance, and compatibility with modern and legacy protection architectures.
The device’s removable terminals and conformal-coated boards simplify maintenance and field servicing, reducing downtime during inspections. Its fiber-based communications improve remote monitoring, lowering on-site visits. The robust protection capabilities help prevent transformer outages, delivering measurable uptime gains and a faster return on asset protection investments.
