FAQs

Install the relay using its projected mounting with removable terminals for straightforward wiring. Connect eight digital inputs, nine digital outputs, and two analog I/O according to your protection scheme. Power the unit from 19-300 Vdc or 40-250 Vac and configure RS485 communication for Modbus RTU or DNP3 RTU, following the Eaton datasheet for termination and addressing.
The relay supports Modbus RTU over RS485 and DNP3 RTU over RS485, enabling straightforward SCADA integration. Map input/output points, configure protection logic, and enable polling for status, alarms, and metering data. Ensure proper baud rate, line termination, and network addressing to avoid communication delays and data loss.
The device includes Voltage Protection and Metering, Differential Protection, Current Protection and Metering, and Power Protection and Metering. These functions support fast tripping for abnormal conditions, provide event logging for fault analysis, and help minimize fault propagation in critical transformer networks.
The relay accepts a power supply range of 19-300 Vdc or 40-250 Vac and operates at 50/60 Hz. It features removable terminals and projection mounting for easy field wiring and installation.
