The article is devoted to the development of a unit for collecting, primary processing and transmitting measurement information for electrical impedance tomography tasks. The developed block provides the ability to connect one of the terminals of the current source to a common point, and the second terminal to any of the electrodes on the surface of the biological object under study; provides the ability to measure the amplitude of potential changes on any of the electrodes on the surface of a biological object relative to a common point. Control is carried out using a control program installed on a personal computer, connected to it via a universal USB port. It is possible to control the current source (amplitude, shape and frequency) through voltage. An experimental verification of the accuracy of generating a control signal for a current source in a given range of frequencies and amplitudes of the control signal was carried out. It has been established that the error in the amplitude of the control signal does not exceed 0.7%, and the error in the frequency of the control signal does not exceed 0.008%.
