Abstract
Abstract The invention relates to an opto-electronic contact mechanism in which a potential of an input circuit is separated from the potential of an output circuit by two optocouplers. The optocouplers contain an excitor circuit having a radiation transmitter and also a radiation receiver optically coupled to the transmitter, all within a common housing. The mechanism utilizes a pulsed operational mode to distinguish normal operation from erroneous operation.
