Get to know the inputoutput modules of the Festo CPX electrical terminal

Festo CPX electrical terminals are used a lot in the field. In the previous article, we have introduced its bus node module CPX-FB33 (how to use the diagnostic function of Festo bus node CPX-FB33?). Today in this article, we will Talk about the input/output module (IO module) of the CPX electrical terminal.

The input/output module (IO module) of the Festo CPX electrical terminal is composed of three parts: the connection block, the electronics module and the interlinking block, as shown in the figure below:

Interlinking block (Interlinking block) is at the bottom of the input/output module, and its function is to establish a mechanical and electrical connection between the valve island and the module;

The electronic module (Electronics module) is in the middle position. It is composed of a circuit board and status display LED lights to complete the transmission and display of electronic signals; The connection block is on the outermost side, and its role is to provide electrical connections for various sockets;

The following picture describes the composition of the three parts of the input/output module in physical form

There are many types of interface modules, such as: CPXAB-8-M8-3POL, CPX-AB-8-M8x2- 4POL, CPX-AB-1-SUB-BU-25POL, CPX-AB-4-M12x2-5POL, etc.

Wait. Take CPX-AB-8-M8-3POL as an example: "CPX" is the model name; "AB" means connection Module (plastic material); "8" means that there are 8 channels; "M8" means that the diameter of the connection isM8; "3POL" means that the number of pins connected to the socket is 3.

There is also a metal (Metal) material interface module, with "M" instead of "AB" in its name, such as: CPX-M-4-M12x2-5POL.

The electronic module includes digital and analog input and output. Common digital input types are: CPX-4DE (4DI), CPX-8DE (8DI), CPX-16DE (16DI); common digital output types are: CPX-4DA (4DO), CPX8DA (8DO), CPX -8DA-H (8DO, high current); there is also a module with digital input/output: CPX-8DE/8DA; analog types include: CPX-4AE (4AI), CPX2AE (2AI), etc. The following two pictures are the appearance of CPX16DE and CPX-2AE:

For most interface modules (with exceptions), you can see the model of the electronic module connected to it and the status of the LED light through the transparent plastic cover on the upper part, as shown in the following figure:

The same interface module, connected to different electronic modules, has different pin definitions. ratio

For example: the same CPX-AB-8-M8-3POL interface module, when it is combined with CPX-8DE (DI) module, the 1st pin of the plug connector is +24V, the 3rd pin is 0V, and the 4th pin is a number Enter Ix as shown in the figure below:

When the CPX-AB-8-M8-3POL interface module is combined with the CPX-8DA (DO) module, the first pin of the plug connector has no connection (NC), the 3rd pin is 0V, and the 4th pin is the output channel Ox, as follows Picture:

It can be seen that the pin definition of the interface module depends on the type of electronic module combined with it. Does this sentence sound familiar? Yes, we have introduced the backplane module of Siemens ET200S. The wiring method also depends on the type of signal module plugged in. If you are interested, please search and see.
