Abstract
The paper examines the technical and economic characteristics of the most common controllers from popular manufacturers in the United States, designed to automate the operation of rod depth pumps installed in oil-producing pumping machines. The main functional components, including sensors and actuators, are presented. A comparative analysis of the functionality is made, namely, the operating modes of the automation systems for switching on and off electric motors of rod pumps.
 The main distinguishing features of the presented controllers is that some of them lack any sensors and in which the dynamograms are controlled in the function of currents and voltages. In addition, there are also types that use radio communication with the main control and control panel, which greatly simplifies wiring diagrams, eliminates the need to install relatively long cable networks.
