Abstract

An optocoupler arrangement for signal transmission with galvanic separation includes a first optocoupler with a first input path and a first output path, a second optocoupler with a second input path and a second output path, wherein the first and second input paths are arranged in series with a connecting switching device, and wherein an actuation circuit has first and second input signals as inputs, and first, second and third outputs as outputs, and the actuation circuit is configured such that, as a function of a first switching state related to the first and second signal inputs, the connecting switching device is actuated, and with respect to either a second or a third switching state, either a first switching device assigned to the first input path of the first optocoupler or a second switching device assigned to the second input path of the second optocoupler is actuated.
