    Hi

    Somewhere can help me?

    I have a industrial equipment that use a two wire 20-45mA Current Loop (pasive, without current source) to comunicate.

    I need make a interface (active with the current source) that transform the current loop to a standar comunication for a microcontroller (RS232 or TTL)

    thanks in advance to anyone who can help me
