Abstract: An input/output module is provided for a bus system having a socket, the five contact cups of which each may comprise an electrical contact, and a measuring device for detecting a connector of a four-wire data cable. The measuring device can be configured to detect, when a connector is inserted into the socket, whether the connector comprises four or five electrical contact pins which are each plugged into one of the contact cups and are electrically connected to the respective electrical contact of the contact cups. The measuring device may be configured to close a first and a second switching device only when five electrical contact pins are detected in order to apply a respective supply voltage from two DC voltage supplies to the corresponding plugged contact pins of the connector plugged into the socket via the respective electrical contacts of the contact cups.
