A universal input/output module may be tailored to enable or disable a pull-up or pull-down function such that distinct type digital signals reaching the digital signal processor may be changed such that the distinct digital signals are similar in nature when processed. The digital signal processor is able to enable or disable a pull-down or a pull-up function to provide the ability to universally handle these distinct digital signal types. In other features, a plurality of the modules may be associated with a common power supply, board controller and central communication bus. The input/output modules have applications such as in processing a switch or sensor signal, and outputting a control signal to an associated component.
