Overview
High-performance digital input modules for National Instruments
CompactRIO embedded systems and R Series expansion chassis
provide industrial logic levels for direct connection to a wide array
of industrial 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.
Advanced Features
Advanced features include internal current limiting and industrial
logic thresholds for direct connection to a wide array of industrial
devices such as proximity switches, emergency stop buttons, level
switches, pressure probes, and magnetic pickups. The NI cRIO-9411
module, ideal for quadrature position encoders, features 5 V/TTL
logic levels with differential inputs up to ±24 V or single-ended
inputs. The cRIO-9411 also accepts 6 to 30 V power and generates
a regulated 5 V output for powering quadrature encoders. The
cRIO-9435 is a universal digital input module that accepts AC and
DC as well as both sinking and sourcing signals up to 250 VAC/VDC.
NI CompactRIO digital input modules connect directly to RIO
FPGA hardware to create high-performance embedded systems that
deliver the optimization and flexibility of a custom electrical circuit
completely dedicated to your I/O application. The RIO FPGA
hardware provides unlimited options for timing, triggering,
synchronization, change detection, digital pattern matching, or

digital communication. For instance, a CompactRIO system can
implement a circuit to detect digital events and record a timestamp,
implement high-reliability digital control logic 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
any CompactRIO embedded system or R Series expansion chassis
• Screw terminals, D-Sub, strain relief, high-voltage cable,
solder cup backshell, and other connectivity options
• NI CompactRIO Extreme Industrial Certifications and Ratings1
• cRIO-9411 module generates regulated 5 V power for quadrature
encoder or other devices
• Channel-to-earth ground double-isolation barrier for safety
and noise immunity

Accessories and Cables
SH68-C68-S Cable – for connecting an
NI cRIO-9151 R Series expansion chassis
to the digital port on a PCI or PXI
R Series device. You can connect up to
two cRIO-9151 chassis to an NI 7831R
device, and up to four cRIO-9151 chassis
to a PXI-7811R device.
Note: Use only the SH68-C68-S digital cable with the cRIO-9151 chassis.

DIN-Rail Mounting Kits – for mounting
Connectivity Accessories
4 or 8-slot CompactRIO embedded chassis
or cRIO-9151 R Series expansion chassis to
any standard 35 mm DIN rail. For high
shock and vibration applications, NI recommends a panel mounting
configuration rather than DIN rail. Panel mounting holes are built
into all CompactRIO Chassis. For detailed mounting instructions,
refer to the CompactRIO Installation Instructions manual for
your chassis.
The CompactRIO system is designed to provide flexible options
for low cost field wiring and cabling. The cRIO-9932 kit provides
strain relief and operator protection from high-voltage signals for
any 10-position screw terminal module. The cRIO-9935 (or other
15-pin D-Sub connector) is required for use with the cRIO-9411
module. The cRIO-9935 includes a screw terminal connector with
strain relief as well as a D-Sub solder cup backshell for creating
custom cable assemblies. The cRIO-9936 consists of 10 screw
terminal plugs for any 10-position screw terminal module. The
cRIO-9937 consists of ten 4-position power supply plugs for
CompactRIO real-time controllers.

Power Supplies
NI offers a variety of UL approved
industrial power supplies. The PS-5 is a
DIN-rail-mountable 24 VDC power
supply that provides 5 A of current and is
rated for operation from -25 to 60 °C.
Two PS-5 supplies can be wired in
parallel to provide up to 10 A. The PS-5 is
recommended for heavy-duty industrial
installations. The PS-4 is a DIN-railmountable 24 V power supply in FieldPoint packaging. The PS-3 and
PS-2 are power supply “bricks” with a universal IEC power input.
The PS-3 can also operate as a float charger for 12 VDC batteries. The
PS-1 is a wall-mount power supply.
