| 摘要 |
The invention relates to a circuit arrangement for the electrical isolation of signal lines, with an input (IN) for applying an input signal, an output (OUT) for releasing an output signal, and an initial branch ( 1 ) with an opto-coupler (OK) for optically coupling the input (IN) to the output (OUT), such that the input (IN) and the output (OUT) are connected in electrically isolated fashion by a second branch ( 2 ) with a capacitor (C 1 ).
