put 0~10V into 4 ~ 20MA voltage-current conversion circuit

Published:2011/5/11 21:53:00 Author:Fiona | Keyword: voltage-current conversion

Circuit Work OP amplifier A2 for the constant current output circuit, current sense resistor R11 produces a voltage at 0.4 ~ 2.0V. A2's input consists of two parts: 0.4V the home side and the input signal, when there is no signal, in order to make the offset is 0.4V, because R3 = 10R4, the VR2 's output voltage must be -4V. Since A2 bias is-0.4V,the A2 input signal must be 0 ~ 1.6V, the two parts together is equivalent to-0.04V ~ 2.0V. Increase the sensitive voltage to make the OP amplifier A1 as attenuator, and its magnification is 0.16. Component selection   (View)
