Output modules in a PLC (Programmable Logic Controller) are designed to convert the output signals generated by the CPU into actionable operator signals. When the CPU processes the programmed logic and determines the necessary action, the output module acts as the interface that sends these signals to the relevant devices, such as motors, lights, or other machinery. By executing the commands from the CPU, output modules play a crucial role in actuating processes and ensuring that the control system functions as intended.

The other options refer to functions associated with different components of a PLC system. The task of transmitting input signals to the CPU is handled by input modules, which take readings from sensors and other inputs. Processing inputs from sensors is also primarily a responsibility of the input modules rather than the output modules. Regulating the power supply is not a function of the output modules; this is typically managed by the power supply unit or other power management components in the PLC system.
