Strange... to me this *IS* simple. Worrying about jitter, DC coupling and duty cycle distortion sound messy and overly complicated to me.
Hi, Win -
Would a Bluetooth link work?

As I had mentioned before, read the fine print, in this case on page 2:
Quote "(2) UL recognition is for 16kV dc for one minute".
As is unfortunately customary these days I do not see a working voltage in the datasheet so you'd have to get that from the manufacturer, preferably in writing.
I'd either PW-modulate it or send it across a barrier via RF carrier (FM-modulated). The barrier could be a loopp antenna setup on both sides or maybe a fiber.

Self-contained near field magnetic induction channels have come into their own. Power consumption looks a lot better than achievable with optical. And the 12kV isolation is well within its range. SNR specs shown below support 12-bit resolution with 20dB to spare and they have plenty of bandwidth for your application. Unfortunately some programming is required.
An unshielded drum core inductor is a damned fine magnetic field sprayer.
Put one on each side of a PCB maybe.
When you're generating ions, which might indicate conduction in the medium, an inductive coupling through that medium is ... dicey, to say the least.
