ABSTRACT:
A versatile output card circuit capable of switching a wide range of voltage levels for use with the central processing unit of a computer or microprocessor controller. The versatile output circuit includes an isolation switching means circuit for electrically isolating a second predetermined range of load voltage while responding to a first predetermined range of signal output voltage by switching the second predetermined range of load voltage to a desired load and an indicating means circuit coupled to and responsive to the isolation switching means circuit for indicating when the second predetermined range of load voltage has been switched to the load.
