Siemens analogue input modules provide an interface for central processing units, to sense a range of voltage and current signals. These signals are then converted into digital values by the module and can be used in programs. This enables the CPU to process variable signals such as pressure, speed and flow.

You'll often see the phrase I/O Module, this is a reference to either an input or output, or both modules.
