ABSTRACT:
For the operation of a technical system having increased safety requirements, all of the apparatus for increasing the safety and the availbility are provided in triple redundancy. As selection and output circuit, three redundant data channels (DE1, DE2, DE3) normally emitting the same information are respectively connected in pairs to three AND elements, each consisting of two optocouplers (OR1/OR4, OR2/OR5, OR3/OR6). The elements of the optocouplers are connected with a relay (RL) by an OR arrangement (WO).
