FIELD: telecontrol, applicable in equipment of telecontrol of semiduplex operation, in which the communication channel or separate equipment units are used in turn both for reception and transmission. SUBSTANCE: device for transmission of control commands uses the first (1) and second (2) objects; the first object (1) has first coder 3, signal A transmitter 4, first switch 5, signal B receiver 6, second decoder 7; the input of first coder 3 serves as device input 6, the output of first coder 3 is connected to the input of signal A transmitter 4, whose output is connected to the first leadout of first switch 5, the second leadout of first switch 5 is connected to the input of signal B receiver 6, whose output is connected to the input of second decoder 7, the output of second decoder 7 serves as second output 9 of the device, the third leadout of first switch 5 is connected to the communication channel; the second object (2) has second switch 10, signal A receiver 11, first decoder 12, second coder 13, signal B transmitter 14, delay unit 16 using series-connected computer 17 and controlled delay line 18; the first leadout of second switch 10 is connected to the input of signal A receiver 11, whose output is connected to the input of first decoder 12, the first output of the latter serves as device first output 15, the second output of first decoder 12 is connected to the input of delay unit 16, which serves as the input of computer 17, the output of controlled delay line 18 serves as the output of delay unit 16 and is connected to the input of second coder 13, the output of second coder 13 is connected to the input of signal 13 transmitter 14, whose output is connected to the second leadout of second switch 10 the third leadout of second switch 10 is connected to the communication channel. EFFECT: enhanced efficiency. 2 cl, 1 dwg
