WBI224F21(4 to 20mA Out Hall Effect Current Transducer) adopts the principle of electromagnetic induction and hall effect to measure the AC and DC current of the power grid in real time. Using mean value conversion technology, precision constant current technology and linear temperature compensation technology, 4 to 20mA Out Hall Effect Current Transducer is converted to standard DC current (Iz) output, and the characteristics of AC and DC current universal, strong overload capacity and high isolation.
