Plasma Tip Voltage Adapter 77ISO 

 

The 77iso boards works with 7866 Integra motion controller to read the plasma tip 
voltage. 

 
 

 

 

 

This adapter accepts 0 to 10volts from the Plasma unit. You must select the proper divider to 

reduce the tip voltage (which are usually in the 300 volts range) down to 0-10 volts range.

 

 

 

If you connect the Tip voltage directly to this unit without a divider, 

the adapter and the motion controller will be damaged instantly.
