Analog output from PowerFlex drive
Analog output from PowerFlex drive
(OP)
I would like to use the analog output (0-10Vdc) from an AB PowerFlex variable frequency drive, which is already connected to a PLC, to syncronize two pieces of equipment. I would like the speed of the downstream equipment to be controlled by the upstream equipment.
I am not sure what the maximum load specifications on the analog output card is but I suspect that I would need some sort of buffer or multiplexer or some other device to protect both the drive and the PLC from external faults on the interconnecting device and to give a high impedance so that the output board is not loaded.
Any suggestions?

Signal converter / isolator link, click here
I would suggest the 3 way isolation in a VFD application.

Better check your particular module to be sure its there.
