    hi friends,
    i want to convert 1-10 vdc input signal to 4-20 mA output signal.Do anyone have the circuit for this.i have seen the ckt to convert 1-5 vdc input signal to 4-20 mA output signal.
    Any response would be appreciated.

    By examining the input resistors, it should be simple to make a scale change and use that circuit for your purpose. Or leave that unchanged and simply reduce your signal voltage by one half.

    A voltage follower is ideal for this.
