Classification: B41F,H03K

Abstract:
A circuit arrangement for the level conversion of binary signals in a control system of a printing-technology machine, comprisinga component for transmitting a signal and a component for receiving the signal, said signal-transmitting component having an element for generating a binary level value and said signal-receiving component having an element for receiving a binary level value; anda window discriminator provided between said signal-transmitting component and said signal-receiving component, said window discriminator having a lower threshold value and an upper threshold value corresponding to binary level values, said window discriminator further having a binary signal input and a binary signal output, said signal input being connected to an output of said signal-transmitting component, said signal output of said window discriminator being connected to an input of said signal-receiving component, said signal input being at a level lying between said lower and said upper threshold values when said element of said signal-transmitting component, for generating a binary level value, is not driven.
