Optocoupler arrangement and input and/or output module

摘要

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.

1. An optocoupler arrangement for signal transmission with galvanic separation, comprising:
a first optocoupler having a first input path and a first output path; a second optocoupler having a second input path and a second output path; a first signal input; a second signal input; a connecting switching device, the first and second input paths being arranged in a series circuit with the connecting switching device such that the connecting switching device connects the first input path to the second input path; a first switching device assigned to the first input path of the first optocoupler; a second switching device assigned to the second input path of the second optocoupler; and an actuation circuit having a first output, a second output and a third output, the first signal input and the second signal input forming inputs of the actuation circuit, the actuation circuit being 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 one of (i) a second switching stated and (ii) a third switching state, the first switching device assigned to the first input path of the first optocoupler is actuated or the second switching device assigned to the second input path of the second optocoupler is actuated.
