I’m considering the Jrk 21v3 for a servo controlled valve project but the 0 – 5v input control (RX) would be supplied from an external system. This system would not be on the same power supply and may not be on a common ground. It would just supply a reference DC voltage between two terminals. Assuming I connect the reference voltage ground to the ground pin on the Jrk and the reference voltage +VDC to the RX pin, would this work?
Thanks,
Gary
