摘要

Improvements in self-diagnostic circuits in the acquisition of analog measurements, of the type that are available in instrumentation and process control, characterized in that the acquisition of measurements is made through an interface circuit that consists essentially of an adapter or filter input, a multiplexing of channels and a digital analog converter, controlling the computer input relays, static or electromagnetic, to perform the acquisition of analog measurements either cyclically or by random access.
