Comparative analysis of instruments and development of a switching circuit for automating the process of recording electrical signals of multichannel systems

Comparative characteristics of measuring instruments for automating the technological process of recording electrical signals of multi-channel systems are considered. The selection of the most optimal tool for automating the technological process of recording electrical signals of multi-channel systems is carried out. The process of developing a circuit for switching channels in a multi-channel system is described. The most optimal scheme for use with the L-Card E-502 measuring module is selected. The implementation of the selected scheme based on eight-channel relay boards is presented. An example of using the selected scheme is given.

Keywords: automation, multi-channel systems, measuring complex.
