    I have an application where i have three 0 to 10v analogue outputs controlling one VFD. The VFD will need operate on the highest analogue value. So if unit A sends 5v , Unit B sends 5.5v and Unit C sends 4.8v then the VFD should operate on the 5.5v. Can i just simply connect all three outputs from units in parallel. All outputs are diode protected.

    As long as all outputs have a series diode for isolation, you should get the effect you're after.

    Be aware that if they're AC outputs then they cannot be diode protected!

    Thx for the reply
    The outputs are all DC
