Universal interface for outputting and recording analog and digital information, has terminal for comparing measured potential with respect to threshold value, outputting digital value and measuring electrical output

摘要

The interface has a terminal (8) whose potential is measured with respect to ground or supply voltage by the interface. The terminal measures an input current according to ground or supply voltage by the interface. The terminal compares the measured potential with respect to a threshold value and outputs a digital value. The terminal regulates an output current according to external pressure. The terminal supplies a regulated voltage according to the external pressure. The terminal measures an electrical output and specifies the output current.
