FIELD: railway transport; signaling and communication.
SUBSTANCE: invention can be used for checking condition of track circuits in automatic interlocking and signaling system devices with electronic interface. According to invention, computing nucleus of each signal converting and processing module contains control signal digital synthesis device to supply control signal through system of external interface to signal converting and processing module. Each signal converting and processing module contains control signal current shaper to provide electrical isolation, create signal similar to signals from track circuit and supply said signal together with signal from track circuit to input of matching element.
EFFECT: enlarged operating capabilities, improved safety of traffic.
