摘要:
Input channel diagnostics for an industrial process control system that provides improved apparatus and methods relating to fault containment, overload protection and input channel diagnostics. The input circuit includes one or more series resistors that have a total resistance that is at least two orders of magnitude greater than the magnitude of the resistance of a conditioned sensor signal source.
