- 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 locking, etc).
Functions
◆ Protection functions: overvoltage, undervoltage, phase sequence, dynamic phase loss, static phase loss, voltage unbalance;
◆ Output of fault signals: general-purpose electric transmission signals; working voltage: 24VDC/VAC.
