This article presented the application of a safety comparator in the track circuit of a railway signaling system for counting the overvoltage caused by voltage fluctuation resulting in the damage of the BR966F2 relay. Overvoltage counting in the track circuit of the railway signaling system using the safety comparator to detect two voltages in the series circuit and the fault of overvoltage of the track circuit were used for detecting the status of the train in the interlocking system of the railway signaling system, and the digital counter circuit displaying the overvoltage status to monitor and confirm the use of the BR966F2 relay of the railway signaling system that resolved the problem causing the track circuit error, minimized the duration for system maintenance, and maximized the reliable performance of the advanced safety system in the track circuit for the control and command functions of the railway’s operations of the State Railway of Thailand.

W artykule przedstawiono zastosowanie układu bezpieczeństwa w obwodzie torowym sygnalizacji kolejowej do zliczania przepięć wywołanych wahaniami napięcia powodującymi uszkodzenie przekaźnika BR966F2. Zliczanie przepięć w obwodzie torowym sygnalizacji kolejowej za pomocą komparatora bezpieczeństwa do wykrycia dwóch napięć w obwodzie szeregowym oraz zwarcia przepięcia obwodu torowego posłużyło do wykrycia stanu pociągu w blokadach systemu sygnalizacji kolejowej oraz obwodu licznika cyfrowego wyświetlającego stan przepięcia w celu monitorowania i potwierdzenia użycia przekaźnika BR966F2.
