Abstract
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 (TN) 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 (C1).
Claims12
A circuit arrangement for the electrical isolation of signal lines, comprising:
- an input (IN) for applying an input signal,
- an output (OUT) for emitting an output signal, and
- an initial branch (1) with an opto-coupler (OK) for optically coupling the input (IN) to the output (OUT),
- wherein:
- the input (IN) and the output (OUT) are connected by a second branch (2) with at least one capacitor (C1), for the purpose of transmitting a changing portion of the input signal;
- and
- an inverter (I1) for driving the capacitor (C1) is connected between the input (IN) and the capacitor (C1).
