Abstract
A field device connection unit has a main body, on which a plurality of connection elements for connection of connecting lines to field devices and a plurality of slots each intended for receiving a respective plug-in unit are arranged. The plug-in unit has a first group of field-side plug contact devices which are connected by the connection elements for connection of connecting lines to field devices, and a second group of system-side plug contact devices which are connected to a higher-level arrangement. For testing of the field device connection unit when the field wiring is disconnected, the plug-in units have a resilient latching cam, which latches switchably in a recess in the main body, the contacts of the second group of system-side plug contact devices being closed and the contacts of the first group of field-side plug contact devices being opened.
