Mesa 7i96s torch on/off connection

I will have to look again. But either way I just need a pinout for the Torch ON/OFF on the mesa board.

How its connected depends on what the 7I96S is driving.

If the 7I96S is driving a relay with less than 100 mA of current
I would use 7I96S OUT5. Also a relay needs a flyback diode.
This may be included in the torch control switch wiring in
the plasma source.


 

Thank you
