Overview
High-performance digital input switching modules for National Instruments
CompactRIO embedded systems, R Series expansion chassis, and
NI CompactDAQ provide industrial logic levels for direct connection
to a wide array of industrial automotive switches and transducers. Each
module features an integrated connector junction box with screw terminal
or cable options for flexible and low-cost signal wiring. All modules
feature the NI CompactRIO Extreme Industrial Certifications and Ratings.
in silicon, or perform redundant safety enforcement and interlocks. Unlike
traditional digital control devices, the performance of a CompactRIO
digital control system does not decrease as the amount of digital logic
increases because of the parallel nature of the RIO FPGA circuitry.
Key Features
• High-performance digital and counter/timer input modules for CompactRIO
embedded system, R Series expansion chassis, or NI CompactDAQ system
• Screw terminal, D-Sub, strain relief, high-voltage cable,
solder-cup backshell, and other connectivity options
• NI CompactRIO Extreme Industrial Certifications and Ratings
• NI 9411 module that generates regulated 5 V power for quadrature
encoder or other devices
• Channel-to-earth ground double-isolation barrier for safety
and noise immunity and channel-to-channel isolation

System Compatibility
You can use NI C Series modules in multiple system types depending
on available software. See Table 1 for CompactRIO and NI CompactDAQ
module compatibility because not all modules work with both systems.
Many of the advanced features described apply only to reconfigurable
I/O systems and not to NI CompactDAQ.
Advanced Features
When used in CompactRIO, C Series digital 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 timing, triggering, synchronization, change
detection, digital pattern matching, or digital communication. For instance,
with CompactRIO you can implement a circuit to detect digital events
and record a timestamp, implement high-reliability digital control logic
