Product Description And Application

WBV344U01-S (Dc Voltage Transducer 4 20mA) converts DC input pure voltage into a load independent output signal DC 0-20mA or 4-20mA.

Dc Voltage Transducer 4 20mA has adopted modulation-demodulation isolation principle and average measurement method for real time measurement of DC voltage from power grid or electric circuit.
