- product introduction:Features
◆ Used for three-phase-three-wire protection and signal transmission;
◆ Output form: general-purpose electric transmission signal (4~20mA);
◆ The constant voltage & constant current source design is suitable for long-distance signal transmission;
◆ Output of transmission signals can be directly connected to PLC, while the traditional sync output from relay contacts is kept;
◆ Troubleshooting is set by the PLC, which receives transmission signals
(e.g. phase loss, delay recovery, fault lock, etc)
◆ Uses voltage-following technology to collect voltage values;
◆ Outputs general-purpose transmission signals for the PLC to set the voltage
protection values and troubleshooting methods.
Functions
◆ Protection functions: phase sequence, dynamic phase loss, static phase loss,
voltage unbalance;
◆ Over-and undervoltage protection is independently set by the PLC according
to the electric transmission signals.
