Patent ID: 6853326

Claim:
Converter having a head part ( 1 ) connectable to an external data bus, one or more connection modules ( 2 ), connectable to the headpart by way of plug-in mounting in the form of rows, and a circuit support ( 8 ) having an electronic circuit, wherein: the head part ( 1 ) has a plug-in connection ( 3 ) with plug-in contacts ( 4 ) contacting an internal data bus; each connector module ( 2 ) has a counter plug-in connection ( 5 ) matching the plug-in connection ( 3 ) of the head part ( 1 ), and the counter plug-in connection ( 5 ) has counter plug-in contacts ( 6 ); counter plug-in contacts ( 6 ) of the counter plug-in connection ( 5 ) are connected via circuit connection contacts ( 7 ) for connection to the circuit support ( 8 ) and to plug-in contacts ( 4 ) for connection of the counter plug-in contacts ( 6 ) of a further one of said connection nodules ( 2 ); each connection module ( 2 ) has at least one device connection ( 9 ) for connection of an actuator or a sensor that communicates via the internal data bus and the external data bus with a control device connectable to the external bus; and a plug-in connection of the connection modules ( 2 ) to one another or of the connection module ( 2 ) to the head ( 1 ), and also the plug-in association of the circuit support ( 8 ) are watertight.
