Output Modules in a PLC (Programmable Logic Controller) are crucial components that serve the function of converting control signals generated by the PLC's internal logic into usable outputs for external devices. When a PLC processes input signals based on its programmed logic, it sends signals to the output modules. These modules then activate or deactivate actuators, such as motors, lights, or solenoids, effectively controlling machinery or industrial processes. This conversion ensures that the commands determined by the PLC can lead to physical actions in the manufacturing environment, thereby making the system operable and responsive to the programmable logic defined in the software.

The other choices relate to different functions not associated with the primary role of Output Modules. For instance, storing the PLC program is managed by the memory of the PLC rather than the output modules. Evaluating program efficiency is a task of the PLC's processing capabilities, not a function of the output hardware, and testing input conditions refers to the role of Input Modules that handle the incoming signals from sensors or switches, rather than the outgoing control signals managed by Output Modules.
