FIELD: mechanic.
SUBSTANCE: device contains stopping and reset electro-pneumatic valve, electro-pneumatic converter of air pressure, microprocessor module for smooth pressure changing, informational assignment interface for required pressure level, galvanically isolated converter of the feedback control signal, power contacts for the electro-pneumatic valve control, discrete channels for electro-pneumatic valve control signals output. The microprocessor module for smooth pressure changing is connected to the informational assignment interface for ensuring the required pressure level and connected through a galvanically isolated converter of the feedback control signal to the electro-pneumatic air pressure converter, and the power contacts for the electro-pneumatic valve control through the discrete channels of electro-pneumatic valve control signals output.
EFFECT: increased quality of car retarder control.
