A discrete signal input device comprises a bus shaper for exchange of information with a control processor device, to which a cathode of current-limiting transistor is connected. The device comprises a second bus shaper, an instruction memory register and two transistors, outputs of the second bus shaper is connected to the first bus shaper and to inputs of the instruction memory register, two outputs of which are connected to bases of incorporated transistors, emitters of which are connected to a circuit with voltage of BODY, collector of which is connected to anode of optron light diode, collector of second transistor is connected to cathode of optron light diode. |
