FIELD: engineering of regulating devices mounted along routes of trains and locomotives. ^ SUBSTANCE: device has voltage source, transistor, controlled by generator, and N light diode circuits, consisting of balanced and serially connected protective diode and K light diodes. Positive pole of voltage source through contact of signal relay is connected to power output of impulse generator, common output of which is connected to negative pole of voltage source and transistor emitter. Between power input of impulse generator and transistor collector N serially connected inductive coils are switched in, first outputs of which are connected to cathodes of protective diodes, and second outputs - to anodes of K light diodes of N light diode circuits. ^ EFFECT: substantially simplified construction and lower costs. ^ 1 dwg |
