The problem of computerization of laboratory experiments and technical implementation of the previously proposed software and hardware system circuit to solve it were considered. The existing range of systems can not completely solve the problem because of the complexity and expensiveness of equipment. Therefore, the problem of software and hardware system development for the laboratory experiment automation with minimum time and financial costs is relevant in our time. The central module of the system is the data reception, processing and transmission module. To create the system prototype, the task to calculate the input digital-to-analog paths of the data reception and transmission module was set. The calculation technique of electrotechnical circuits, allowing to obtain accurate values of electronic components, providing the necessary technical characteristics of the system as a whole was presented. The measurement accuracy is 1%, the input signal sampling frequency is 2000 samples per second per channel, the gain range is 1...1000, protection of input circuits from the high input voltage is up to 150V.
