FAQs

Begin with ensuring power is isolated, mount the unit using semi-flush installation, and connect the removable terminals. Use the ETR-4000 base relay if needed for compatibility. Map the 8 digital inputs and 9 outputs to your control system, and verify 19-300Vdc or 40-250Vac supply compliance. This layout minimizes wiring and simplifies future maintenance.
The device supports Modbus RTU or DNP3 RTU over fiber optic ST, enabling EMI-immune, secure remote communication. Connect the appropriate RTU channel to your SCADA or MES, then configure tag mapping for 8 inputs, 9 outputs, 2 analog inputs, and 2 analog outputs. This streamlines data collection, alarm handling, and asset monitoring.
Key protection functions include Differential Protection, Voltage Protection and Metering, Power Protection and Metering, and Current Protection and Metering. The system supports Zone Selective Interlocking and provides Trip Coil Monitor and Sensitive Ground Input options, delivering fast, selective clearance and improved fault localization in transformer networks.
Power supply range covers 19-300 Vdc and 40-250 Vac with 50/60 Hz operation. The unit offers 8 inputs, 9 outputs, plus 2 analog inputs and 2 analog outputs for metering and control. Terminals are removable for easy field wiring, and mounting is semi-flush to fit standard panels with minimal clearance.
