Inlay element, a module termination unit, an input/output device, a modular process control system and a method for assembling an input/output device

A module termination unit, comprising:

• a connection port for housing at least one input/output unit;
• a recess formed in the termination unit, wherein the recess is configured to hold an inlay element;
• wherein the inlay element comprises:
• a first connector section, wherein the first connector section comprises a connection interface for a controller module;
• and
• a second connector section, wherein the first connector section is configured to be connected to the controller module, wherein the second connector section is configured to be connected to a fieldbus device or to a control network, wherein the controller module is connected to the module termination unit by the connection port and to the inlay element by the connection interface, wherein the inlay element is configured to be arranged inside the recess of the module termination unit, the module termination unit has no direct signal connection and/or electrical connection to the inlay element, and wherein the inlay element forms a bridge between the controller module and a connected fieldbus device or connected control network.

A method for assembling an input/output device, comprising:

• providing a module termination unit, the module termination unit comprising at least one connection port for housing at least one input/output unit and a recess formed in the termination unit, wherein the recess is configured to hold an inlay element, wherein the module termination unit has no direct signal connection and/or electrical connection to the inlay element;
• arranging an inlay element inside the recess of the module termination unit, the inlay element comprising a first connector section and a second connector section, wherein the first connector section is configured to be connected to a controller module, wherein the first connector section comprises at least one connection interface for the controller module, and wherein the second connector section is configured to be connected to a fieldbus device or to a control network, wherein the inlay element forms a bridge between the controller module and a connected fieldbus device or connected control network;
• and
• connecting the controller module with the module termination unit and the inlay element by inserting controller module into a respective socket by the at least one connection port and the at least one connection interface.
