2-lead separator of electric current signals, equipped with start-up system, connected with multi-vibrator, whose two outputs are connected through two keying elements with furthermost outputs of divided, primary voltage winding of a transformer, secondary winding of which is connected in series with the transformer's primary current winding and a system of two-half rectifier loaded with controlled two-terminal network. It is characterised in that the current transformer (7) has divided secondary winding and the furthermost ends of this winding are connected with emitters of two transistors (10, 11), whose collectors are joined together and at the same time connected with one terminal of the condenser (12), with one current input (D) of the start-up system (2) and with the middle output of the primary voltage winding of the transformer (6), while bases of the said transformers (10 and 11) are joined together and at the same time are connected with other terminal of the said condenser (12) and directly, or through the two-terminal network (13) with the first output clamp (C) of the whole system and with the second current input (I) of the start-up system (2), while the emitter of each of the above transistors (10 and 11) is connected with respective control input (G, H) of the start-up system (2).<IMAGE>
