With many data acquisition (DAQ) devices to choose from, it can be difficult to select the right one for your application. This white paper outlines five questions that you should ask when selecting your hardware.
Products & Services
I/O Modules and Instruments
Data acquisition I/O devices have both input and output functionality. Digital or discrete I/O modules include on-off signals used in communication, user interface, or control.
Data Output Modules
Data output modules or cards transfer amplified, conditioned, or digitized signals.
Data Input Modules
Data input modules accept sensor and other signal output for data acquisition systems. They may include signal conditioning prior to the analog-to-digital conversion stage.
Data Loggers and Data Recorders
Data loggers and data recorders acquire digital data from sensors and other signals. They are primarily used to store data for subsequent downloads to a host PC, but may also include real-time features such as monitors and alarms.
Data Acquisition Computer Boards
Data acquisition computer boards are self-contained printed circuit boards that typically plug into the backplane, motherboard, or otherwise interface directly with the computer bus.
