Data acquisition hardware conditions the signal and then converts it into a digital number by employing an analog-to-digital converter.
This digital value is stored by the computer.
Data acquisition systems are often able to directly handle low-voltage inputs that are, to say, a few millivolts up to a few volts..
Analog outputs are predominantly used to control actuators, valves, and motors in industrial environments.
Standard analog output ranges provided by these programmable logic control (PLC) systems include: 5 V, 10 V, 0″10 V, 4″20 mA, and 20 mA..
An example of an analog output is the output from the DCS to converters.
When a current to a pneumatic (input) converter in the field in a hazardous area signal is to be sent from the DCS, a grounded barrier may be used..
Program a DataAcquisition for ADALM1000 input and output.
Use the Analog Input Recorder app to visualize and record analog input signals.
This example shows how to acquire data from multiple channels, and from multiple devices on the same chassis.
This example shows how to acquire and plot data from an NI USB-9219 device.
This topic shows how to use the Analog Output Generator app to define and generate signals from an audio device.
To open the Analog Output Generator, on the MATLAB ® Toolstrip, on the Apps tab, in the Test and Measurement section, click Analog Output Generator.
