ABSTRACT:
A control device utilizing multidigit binary coded position signals generated in a selected sequential format by a position transmitter to indicate the position of an element movable between limits in increments of the travel path of the element. The position signals are supplied to a comparator device. A process signal reflective of a range of a process condition is supplied as a binary coded digital process signal to a reference device which generates digital binary coded command position signals in selected sequential format compatible with the binary coded position signals so each binary coded command signal indicates a desired position of the movable element. The binary coded command position signals are supplied to the comparator device. The comparator device compares the binary coded position signal and the current current binary coded command position signal and in the event of a mismatch operates an actuator device to move the movable element to the current binary coded command position selected by the reference device. The process signal can be divided into several different control ranges and in each range a series of command position signals can be generated in response to the process signals.
