FIELD: railway automation.
SUBSTANCE: invention relates to control means for relay windings of railway automation. The technical solution is a module for controlling relay windings of railway automation, made with the ability to safely determine the position of the relay contacts using the encoded signal of the external control module and safely control the relay windings, containing comparators for monitoring the integrity of the winding of controlled relays, the module is equipped with four galvanically isolated converters of input DC voltage to output DC voltage with the ability to control four safe comparators, and the safe comparators are designed to receive a control signal through an address decoder and a control word encoder.
EFFECT: provided is possibility to realize control of relay windings of railway automatics without determining the position of the contacts of the relay for monitoring the integrity of the winding with an increase in the safety of control circuits.
