Abstract

A comparative analysis of measuring devices for the recording data process automation from the multichannel electrical signals system in reception and emission modes is carried out. The process of developing a general circuit for switching channels based on the multiplexor circuit is described. The process of developing a circuit for switching channels in a multichannel system and the choice of the emission and reception modes are described. The process of developing a circuit for switching channels with additional power amplification and control system signals amplification modules is described. The process of developing a switching circuit for an electrical signals multichannel system based on eight-channel relay modules is described. The implementation of the selected circuit based on eight-channel relay boards is presented. The choice of the most optimal switching scheme of a multichannel system of electrical signals in the emission and reception modes for use with the L-Card E-502 measuring module has been carried out. An example of using the developed switching scheme for a multichannel system of electrical signals based on eight-channel relay modules is presented.
