Railway transport control systems make extensive use of electromagnetic and electromechanical relays to ensure the safe operation of train traffic. However, the widespread use of these components increases the likelihood of faults and failures. To mitigate these risks, it is essential to monitor and analyze the parameters of railway automation relays regularly. This article presents the development of a functional scheme of an automated complex designed for testing and analyzing the electrical and timing parameters of relays used in railway automation systems.
