Microprocessor Analog I/O Modules

Abstract

The article considers the possibilities of algorithmic solutions when creating interfaces based on microcontrollers, which make it possible to reduce the number of mandatory procedures in the organization of multiplex channels with galvanic isolation. The issues of elimination of interferences that affect the accuracy of measuring input signals in the measuring channels are considered. Methods for input and processing of signals in the form of currents and voltages in analog modules of measuring channels of the control system are presented.
