I would like to switch the output of a tens unit to 8+ different outputs.

 

"Max frequency output is 150 Hz."

 

"I would probably want to be switching at ~1000 Hz."

Something is not right here. It seems to me that you think you can use one TENS machine to do the job of eight+ by switching fast enough. I can see a few problems:

  • You will no longer be applying a 150 Hz signal to the skin. You will be applying a 1 kHz signal modulated at 150 Hz.
  • The average current will fall to 1/8 of the current in correct use (if everything else goes well).
  • The TENS unit is probably running a constant current generator circuit. Rapid switching of the load will probably cause havoc with the internal regulation.

Note: SI Units named after a person are capitalised when abreviated and lower-case when spelled out. "V" for volt, "Hz" for hertz, etc.
