Abstract
An intrinsically safe touch screen system includes a touch screen, a current limiting barrier coupled to the touch screen, a touch screen controller, and a voltage limiting barrier. The controller is coupled to the current limiting barrier, the voltage limiting barrier, and the touch screen, in a configuration such that signals transmitted to and from the touch screen will be within a level that ensures intrinsic safety of the touch screen.
