What type of data would a Digital Output module control?

A Digital Output module is specifically designed to control discrete ON/OFF signals. This type of module communicates with devices like relays, solenoids, or other binary devices that only require two states: either activated (ON) or deactivated (OFF).

Digital outputs work with binary values, which are fundamental in control applications where devices respond to simple on-off commands. This means that for any system using a Digital Output module, the output will either provide sufficient power to turn a device on or not provide any power at all, effectively turning it off. This is distinct from analog signals, which involve varying voltages, or continuous signals that represent a spectrum of values.

While other options refer to types of signals that a Digital Output module does not handle, the focus on discrete ON/OFF signals accurately reflects the primary purpose and function of such a module in automation and control systems.
