National Instruments

Rabwellplc stocks National Instruments hardware for engineering teams running CompactRIO, CompactDAQ, and PXI test, measurement, and control systems. Our NI inventory targets two buyer profiles: maintenance and validation engineers replacing failed controllers or C Series modules in installed systems where lead time matters more than configuration choice, and OEM test stand builders sourcing complete cRIO + C Series + cDAQ bills of materials against a single PO. Given NI's product line transitions in recent years, we focus on keeping legacy Linux RT cRIO controllers (9022, 9068, 9074, 9082) and the current performance line (9035, 9038, 9039, 9045, 9047, 9049, 9056, 9057) available together so a like-for-like replacement is in stock when a system fails.

How to Choose

For CompactRIO, three decisions: (1) processor and FPGA performance — cRIO-9035 dual-core / Kintex-7 sits at the entry of the current performance line, cRIO-9038 quad-core / Kintex-7 on the high end, cRIO-9057 dual-core Zynq is the value point; (2) slot count — 4-slot (9063, 9066) for compact assets, 8-slot (9035, 9038, 9067, 9068, 9074) for full data acquisition stacks; (3) OS — Linux RT on every current controller and on cRIO-9068 in the legacy line, NI Linux RT or VxWorks on older devices. Project archives written in LabVIEW Real-Time for VxWorks must be ported to Linux RT before deploying on a current controller.

For CompactDAQ, the question is bus architecture against host application: USB chassis (9171/9174/9178) for benchtop and short-distance with a Windows/Mac LabVIEW host, Ethernet chassis (9181/9188) for distributed installs, TSN Ethernet (9189) for time-synchronised distributed measurement.

For C Series modules, identical modules work on cRIO and cDAQ chassis. Selection follows the field signal: signal level (mV/V vs. ±10 V vs. ±60 V), accuracy, channel count, isolation, and sample rate. Match the input range to the sensor and confirm whether the application needs simultaneous sampling (NI-9215 and 9239 simultaneous; NI-9201 and 9205 multiplexed).

For PXI and PXIe, application is benchtop ATE or production test: PXI for 1990s-era and lower-bandwidth installations, PXIe for current high-throughput RF, T&M, and semiconductor test.

Every cRIO and PXIe controller is powered up, BIOS/firmware verified, and confirmed it boots NI Linux RT or NI VxWorks before ship. Standard 12-month warranty. We do not preload customer LabVIEW projects; the unit ships in the factory state.

Frequently Asked Questions

Q: What is your typical lead time for NI parts?

A: Stocked cRIO controllers (9035, 9038, 9057, 9068, 9074), the popular cDAQ chassis (9174, 9178, 9189), and high-volume C Series modules ship in 1–3 business days from our US warehouse. Long-tail SKUs — cRIO-9002, 9004, 9022, the PXIe controllers, and rare strain or sound/vibration C Series — source in 5–15 business days. We confirm ETA per line on the quote.

Q: Are these new NI original or refurbished?

A: All NI hardware we sell is original National Instruments product. We carry both factory-new sealed and tested pre-owned, with condition stated per listing. Tested controllers and chassis are powered up to confirm they boot the shipped NI Linux RT or NI VxWorks image and that all slot signal lines pass loopback. We do not sell counterfeit or relabelled NI hardware.

Q: What warranty applies?

A: 12-month standard warranty from invoice for new and tested pre-owned, covering manufacturing defect and DOA. Returns require RMA initiated within 30 days. Extended 24-month coverage available for project orders.

Q: Will my LabVIEW project deploy onto a controller bought from you?

A: For controllers in the same OS family (Linux RT to Linux RT, VxWorks to VxWorks) and the same FPGA target, yes. Cross-OS migration (e.g., a project written for cRIO-9074 VxWorks moving to cRIO-9035 Linux RT) requires recompiling the LabVIEW Real-Time and FPGA VIs in a current LabVIEW Real-Time and LabVIEW FPGA Module install with the controller's NI-RIO driver targeting the new chassis. Send the LabVIEW version and target controller and we will flag known compatibility traps before you commit.

Q: Do C Series modules from cDAQ work in cRIO chassis?

A: Yes — C Series modules are physically and electrically identical across cRIO and cDAQ. Driver model differs: in cDAQ, modules are accessed via DAQmx; in cRIO, via NI-RIO with the I/O variable served from the FPGA target. Code is not portable across the two driver models without rewrite.

Q: Do you provide LabVIEW driver versions and datasheets?

A: Each NI listing links to the manufacturer datasheet and to the NI-RIO / NI-DAQmx driver version that introduced support for the SKU. We forward NI's Product Compatibility for LabVIEW table on request and can confirm whether a specific LabVIEW + NI-RIO + chassis combination is supported before ship.

Q: Do you offer project pricing for OEM test stand builders or system integrators?

A: Yes. BOMs of 10+ lines (typical cRIO + chassis + 6–12 C Series + accessories) qualify for tiered project pricing and reserved stock. Email the BOM to sales@rabwellplc.com.

Q: Are PXIe chassis and controllers shipped with PXI Platform Services drivers?

A: PXIe chassis and embedded controllers ship in the manufacturer state. PXI Platform Services and the controller-specific NI device drivers must be installed by the buyer from ni.com — we do not preinstall LabVIEW or driver software, but we can confirm the controller boots Windows or NI Linux RT before ship and provide the BIOS/firmware version.
