Electropneumatic control device and electropneumatic subassembly

摘要

In a electropneumatic field device, an electrical field input and a pneumatic supply input are provided. At least one field output is provided at which a field output signal is output based on a field control signal received via the electrical field input. A group comprising at least two modular components of different functionality is provided and at least one modular slot for occupation with either of said modular components from said group. The at least two modular components of the group and the at least one slot are modularly adapted to one another such that interfaces of the slot and interfaces of either of said modular components in the seat merge into one another when the slot is occupied with either of said modular components so that the modular component which is in the slot is connected to the electrical field input and to the at least one field output.

1. An electropneumatic field device, comprising:
an electrical field input; a pneumatic supply input; at least one field output at which a field output signal is output based on a field control signal received via the electrical field input; a group comprising at least two modular components of different functionality and at least one modular slot configured to be occupied with either of said modular components from said group, said at least two modular components of the group and the at least one slot being modularly adapted to one another such that interfaces of the slot and interfaces of either of said modular components in the slot merge into one another when the slot is occupied with either of said modular components so that the modular component which is in the slot is connected to said electrical field input and to said at least one field output; and an identification apparatus that is configured to detect if a type of modular component inserted in said at least one modular slot is a pneumatic component or an electrical output component, and if the modular component inserted in said at least one modular slot is the electrical output component, an interface of the at least one modular slot connected to the pneumatic supply input is blocked in an air tight manner.
