Abstract :
The availability of low cost, reliable, microprocessors has substantially reduced the cost and widened the applicability of digital control. This paper describes a custom MOS IC that fulfills the need of a modern, microprocessor based digital system to have a reliable, cost effective, interface between the microprocessor, operator, and valve.
