Outputs Analog Outputs Analog output (AO) are for variable level or range of output between OFF or stopped and ON or full speed as for an electric motor for instance. Examples of analog outputs are a VFD (Variable Frequency Drive), a valve position actuator, and a industrial variable power supply. The analog outputs (0-10V or 0-20mA) have a 10-bit digital resolution.
