Using the cDAQ Controller
The cDAQ controller consists of four parts—C Series module(s), the cDAQ module interface,
the STC3, and the processor board—as shown in Figure 1-21. These components digitize
signals, perform D/A conversions to generate analog output signals, measure and control digital
I/O signals, and provide signal conditioning.

C Series Module
National Instruments C Series modules provide built-in signal conditioning and screw terminal,
spring terminal, BNC, D-SUB, or RJ-50 connectors. A wide variety of I/O types are available,
allowing you to customize the cDAQ controller to meet your application needs.
C Series modules are hot-swappable and automatically detected by the cDAQ controller.
I/O channels are accessible using the NI-DAQmx driver software.
Because the modules contain built-in signal conditioning for extended voltage ranges or
industrial signal types, you can usually make your wiring connections directly from the C Series
