Abstract
A circuit configuration for potential-free signal transmission has a transformer with a primary winding and a secondary winding. A drive circuit is connected upstream of the primary winding and a selection circuit is connected up to the secondary winding and is driven by pulses. A latching circuit is connected downstream of the selection circuit and prevents a forwarding of second pulses under specific conditions. Finally, a storage element generates an output signal.
