    Ground isolation using opto couplers

    Dear friends..

    I m using a +15V supply for two applications. the +15v is generated from a single supply. I need to isolate the +15V suppy grounds for the two applications. Is it possible to isolate using opto couplers...

    If so schematics please...

    Whether any other ways are there..

    Re: Ground Isolation

    If you need to isolate two circuits you not only have to isolate grounds but +15V, too ..
    Depending on power requirements you may consider 1W, 2W or as needed, miniature dc-dc converters .. Input:12-15V .. Output:15V ..

    Here are some examples:
