Sunyuan SY 4-20mA-O is a kind of low cost small size 2-wire passive 4-20mA to voltage conversion IC, it can convert active 4-20mA signal input into voltage signal output. In designing the converter, 2-wire input loop powered technique is adopted, and the external power supply is not required which simplifies customers' design plan and reduce customers' cost. Inside the conversion IC, current signal conversion circuit, power inverting circuit, subtraction circuit and buffered output circuit are integrated. Very low input equivalent impedance enables the IC to collect current signals from sensor signal output loop circuit and when the input is 30mA signal the voltage drop is ≤6V. That 2-wire passive 4-20ma to voltage conversion IC achieves long-distance non-distorted transmission without external power supply.
