FAQs

Install using the semi-flush mounting method with removable terminals for quick field servicing. Wire 8 digital inputs and 9 digital outputs according to the device’s terminal assignment, and ensure the power supply is within the 19-300Vdc or 40-250Vac range. Use RS-485 for Modbus RTU or DNP3 RTU communication to ensure reliable control and monitoring.
The unit supports Modbus RTU or DNP3 RTU over RS-485, enabling seamless integration with existing SCADA and PLC networks. This enables remote monitoring, diagnostics, and interlocking logic without additional protocol gateways, reducing integration time and potential points of failure.
Yes. Designed as a transformer protection relay, it handles protection, metering, and communication tasks within one device. Its eight inputs, nine outputs, and configurable protection parameters support reliable fault detection, zone selective interlocking, and compatible operation with 50/60 Hz systems.
