Hi All,

   Do we have 4-20mA isolation solution /TI deisgn , the input is 4-20mA and output is 4-20mA, with isolation between input and output , can have a 24V power to this solution . 

Thanks!

    Hi Sheldon,

    are you looking for a complete analog signal chain?

    What is often implemented is a solution where you convert the 4-20mA signal to digital using an ADC (e.g. ADS1220), then transmit the data using a digital isolator or transformer over the isolation barrier and then convert the signal back to analog using a DAC or PWM+filter implementation. You would have to use an MCU then on one (or both) of the isolated sides.

    Regards,
