    isolated 4-20ma

    in making 4-20mA loop powered ransmitters,how we can design the isolated data/power circuit?we have 4mA current at maximum! how we can make isolated dc/dc converter?

    4-20ma isolated

    They are custom designe to the respective specifications. For signal loop isolation, loop powered islators are available as standard components. You can get an idea of the used technique from the schematic diagram:

    isolated 4 20ma

    Hi

    Use a serial D2A converter with the XTR11x (TI) and isoleate the digial interface using opto-cuplers

    All the best

    4-20ma module + isolated

    I want to design an isolated 4-20mA loop powered transmitter,But how I can design the power/data isolation ,I have Max 4mA for all thing.

    Is there any IC or components for isolation?

    analog devices have some parts but they are not suitable for 4-20mA loop,because they need more than 4mA.
