FIELD: electrical equipment.
SUBSTANCE: invention relates to the field of electrical equipment and can be used in the rail vehicle motor-driven door electronic circuit (1, 1a... 1i). Rail vehicle motor-driven door secure closing electronic circuit includes sequential circuit from the first non-linear element (D1) and the first controlled contactor (S1, T1) in the drive motor (M) connection point (A1, A2). First non-linear element (D1) polarity is such that its resistance to the produced by the said drive motor (M) dynamic braking electric current is greater during the door (5) closing than during the door opening. Presence of the supply voltage (U1) for the door (5) acts on the first contactor (S1, T1) resistance change compared to its resistance in the absence thereof. Invention also relates to the rail vehicle (10) door module (3) including the said electronic circuit (1, 1a... 1i), to the rail vehicle (10) with the said door module (3), and to the electronic circuit (1, 1a... 1i) application.
EFFECT: prevention of the rail vehicle undesired door opening with manual manipulation and power failure.
