Research work results of measuring channels design for the control systems based on the integrated magnetic converters (IMC) of the angular displacements are presented in this article. The comparative descriptions of functionality and metrological performance of the integrated magnetoresistive bridge converters is made. The functional and circuit solutions for measuring channels of angular displacements for the control system based on new series PLC Simatic S7-1200 are offered. The progect of data collection system based on integrated magnetic converters and “Siemens” hardware and software is developed.
