Abstract: The innovation applies to a switch logic module (1), which can be electrically and mechanically connected to and disconnected from I/O modules (2) that are arranged next to each other, whereby the I/O modules have an electrical contact and the mechanical connection can be established using the electrical contacts. According to the innovation, a multiplex logic is provided that can be used to connect the electrical contacts of the I/O modules cyclically for a predefined switch time to an output (8) of the switch module. This provides a space-saving and cost-effective solution that can be used to cyclically switch multiple electrical signals to one output with little installation effort and great flexibility.
