In situations where the existing I/O ports of the main controller are insufficient, I/O expansion modules are used. They provide additional capacity to handle more signals and enable the integration of a wider range of sensors that measure parameters such as temperature, pressure or position. Likewise, these modules facilitate the control of additional actuators or output devices, improving the system's ability to interact with its environment.

I/O expansion modules are particularly useful in scenarios where the complexity of the automation process requires a greater number of input and output connections. Their modular design allows easy integration into the existing control architecture and simplifies expansion without the need to replace the main controller.
