FAQs

Begin with power-down and verify supply within the 19-300 Vdc / 40-250 Vac range. Mount the unit using projection mounting, connect 8 digital inputs and 9 outputs, then attach the fiber optic ST link for Modbus RTU or DNP3 RTU. Ensure terminal blocks are securely seated and test the communication path with a simple read/write test from the SCADA host.
Key specs include 8 digital inputs, 9 digital outputs, 2 current sensing inputs, a 50/60 Hz frequency rating, and a power supply range of 19-300 Vdc or 40-250 Vac. It supports Modbus RTU or DNP3 RTU communications over fiber, with a robust transformer protection set suitable for industrial and utility environments.
Yes. The device is designed for transformer protection and metering, offering 8 inputs and 9 outputs, multiple communication options, and protective features like Trip Coil Monitoring and Sensitive Ground Input.
