    Greetings everyone, I'm new here and I've got a problem I hope someone can help me with. I am a bench technician with a service company that repairs industrial controls (drives of all sorts, PLC’s etc.). I have been tasked with keeping a large number of obsolete units functioning which has been fairly easy until now. The original supplier of the current sensors used in these drives no longer produces them and after a lengthy search I have found something close but…….


    The original CS has unipolar +15v input with 0-100mV output. The potential replacement shares the input spec. but the output has a 4V span with a 7V offset (7-11V). Dealing with the offset is simple enough but how do I get 0-100mV from 1-4V? This seems like it should be a common problem with a straightforward solution but I haven’t found a soul who can help.

    How much current does the 0-100mV need to supply?
