The NI PXI-7852R multifunction RIO module features a user-programmable FPGA chip for onboard processing and flexible I/O operation. You configure all analog and digital functionality using NI LabVIEW graphical block diagrams and the LabVIEW FPGA Module. Your block diagram executes in the hardware, giving you direct, immediate control over all I/O signals to deliver high-performance capabilities such as the following:
-Complete control over the synchronization and timing of all signals and operations
-Custom onboard decision making that executes with hardware-timed speed and reliability
-Digital lines individually configurable as inputs, outputs, counter/timers, pulse-width modulation, flexible encoder inputs, or specialized communication protocols
NI R Series multifunction RIO devices feature a dedicated analog-to-digital converter (ADC) per channel for independent timing and triggering. This offers specialized functionality such as multirate sampling and individual channel triggering, which are outside the capabilities of typical data acquisition hardware. Common examples include custom discrete and analog control, sensor simulation, rapid prototyping, hardware-in-the-loop (HIL) test, digital protocol emulation, and other applications that require precise timing
and control.
Required Software This product requires the LabVIEW FPGA Module Version 8.5.1 or later and NI-RIO Version 2.4 or later driver software.
New Virtex-5 FPGA The new Virtex-5 field-programmable gate array (FPGA) architecture is optimized to execute faster and more efficiently using single-cycle timed loops in LabVIEW FPGA. This means you can optimize more LabVIEW FPGA code to fit within Virtex-5 FPGAs and execute more operations per clock cycle.
Recommended Accessories The NI SHC68-68-RMIO cable is designed and shielded specifically for the multifunction I/O connector (connector 0) of R Series devices. The NI SHC68-68-RDIO cable is designed and shielded specifically for the digital I/O connectors (connectors 1 and 2) on R Series devices to reduce crosstalk for improved signal integrity and noise rejection.
Low-Cost, High-Performance Signal Conditioning The NI 9151 R Series expansion chassis connects directly to any digital connector on R Series devices and houses up to four NI C Series I/O modules for low-cost signal conditioning, I/O channel expansion, and direct connectivity.

NI PXI-7852R Packages
To use the NI PXI-7852R , you need all items in the diagram below. Select Option 1 if you already own a PXI System, or Option 2 if you do not already own a chassis, controller, or software.
Roll over the icons below to learn why you need each item in the system
Choose from hundreds of specialized instruments to create a PXI System that suits your measurement needs and can scale for future applications. Then, we'll help you choose the right hardware and software to complete your configuration.
Add More Measurements and I/O Modules Use the PXI Advisor to choose from a variety of modules including analog I/O, digital I/O, switching and more. Then, complete and price the PXI System.
Preview a Complete System View and price a complete PXI configuration including the NI PXI-7852R, chassis, and controller. Starting from the default configuration, you can add modules, accessories, and software and customize your system.
Since your device does not have direct signal connectivity, you need a connector block to act as an interface between your sensors/signals and your device. A connector block provides easy access to the inputs and outputs of your hardware.
You need a cable to transmit signals between your device and your signal connections on your connector block.
The chassis provides rugged, modular housing for the controller and modules and contains the high-performance PXI backplane, which includes the system's data, timing, and triggering buses.
The controller runs your application and interfaces with your PXI modules.
This device requires the LabVIEW FPGA Module (sold separately) and NI-RIO driver software (included with the hardware). LabVIEW and the LabVIEW FPGA Module deliver graphical development for field-programmable gate array (FPGA) chips on NI reconfigurable I/O (RIO) hardware targets.
