Single Phase AC Current Transducer (Two-Wire System), NB-AI1B2-D4EC

AI1B2-D4EC series is a Two-wire transducer that detects AC current in a wire, and generates a signal proportional to that current. The generated signal is 4-20mA,which can be then used to display the measured current in an ammeter, or can be stored for further analysis in a data acquisition system, or can be used for the purpose of control. The output(4-20mA) terminals and power-supply(DC 24V) terminals are combined to save wires.
