Hi

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.

Thanks

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!
