Application and Technology
High-accuracy NI C Series analog input modules for NI CompactDAQ and CompactRIO provide high-performance measurements for a wide variety of industrial, in-vehicle, and
laboratory sensors and signal types. Each module includes built-in signal conditioning and an integrated connector with screw terminal or cable options for flexible and low-cost
signal wiring. All modules feature CompactRIO Extreme Industrial Certifications and Ratings.
C Series Compatibility
The C Series hardware family features more than 50 measurement modules and several chassis and carriers for deployment. With this variety of modules, you can mix and match
measurements such as temperature, acceleration, flow, pressure, strain, acoustic, voltage, current, digital, and more to create a custom system. Install the modules in one of
several carriers to create a single module USB, Ethernet, or Wi-Fi system, or combine them in chassis such as NI CompactDAQ and CompactRIO to create a
mixed-measurement system with synchronized measurements. You can install up to eight modules in a simple, complete NI CompactDAQ USB data acquisition system to
synchronize all of the analog output, analog input, and digital I/O from the modules. For a system without a PC, CompactRIO holds up to eight modules and features a built-in
processor, RAM, and storage for an embedded data logger or control unit. For higher-speed control, CompactRIO chassis incorporate a field-programmable gate array (FPGA)
that you can program with NI LabVIEW software to achieve silicon-speed processing on I/O data from C Series modules.
Advanced Features
When used with CompactRIO, C Series analog input modules connect directly to reconfigurable I/O (RIO) FPGA hardware to create high-performance embedded systems. The
reconfigurable FPGA hardware within CompactRIO provides a variety of options for custom timing, triggering, synchronization, filtering, signal processing, and high-speed
decision making for all C Series analog modules. For instance, with CompactRIO, you can implement custom triggering for any analog sensor type on a per-channel basis using
the flexibility and performance of the FPGA and the numerous arithmetic and comparison function blocks built into the LabVIEW FPGA Module.
Key Features

Connectivity Accessories
NI recommends the NI 9932 or 9236 strain-relief connector accessory for use with the NI 9203.
NI CompactDAQ and CompactRIO systems are designed to provide flexible options for low-cost field wiring and cabling. Most C Series modules have a unique connector block
option that offers secure connections to your C Series system. Table 2 contains all of the connector blocks for C Series I/O modules.
The NI 9932 kit provides strain relief and operator protection from high-voltage signals for any 10-position screw-terminal module.
