To perform analog input measurements, install a supported analog input C Series module into any slot on the cDAQ chassis. The measurement specifications, such as number of channels, channel configuration, sample rate, and gain, are determined by the type of C Series module used. For more information and wiring diagrams, refer to the documentation included with your C Series modules.

The cDAQ chassis has three AI timing engines, which means that three analog input tasks can be running at a time on a chassis. An analog input task can include channels from multiple analog input modules. However, channels from a single module cannot be used in multiple tasks.

Multiple timing engines allow the cDAQ chassis to run up to three analog input tasks simultaneously, each using independent timing and triggering configurations. The three AI timing engines are ai, te0, and te1.
