Equipment and spare partsBrowse manufacturers Search by manufacturerDATA ACQUISITION, MEASUREMENT AND TEST
Source NI equipment for a measurement bench or test system. Specify signals, channel count, speed and synchronization requirements. Modules, chassis, drivers and software are checked against the exact configuration.
Start with signal type and test-system architecture. Similar module names do not establish channel count, accuracy, speed or compatibility; check the complete product designation.
A PXI system combines chassis, controller and instrument modules. PXIe-1081 has hybrid peripheral slots; the older PXIe-1082 has a different slot arrangement. Check compatibility for each slot type.
For selection: Chassis and controller models, module list, slot types, power and cooling; full part number and markings for a replacement.
PXIe-4322 provides voltage and current analog outputs with channel-to-channel isolation. PXI-4072 is a digital multimeter with a digitizer mode. Select by the signal to be measured or generated.
For selection: Function, range, accuracy, channel count, synchronization and chassis; installed module marking and calibration requirements. Example: PXIe-4322 part number 782878-01.
PXI-2530B is a reed-relay switch with multiple multiplexer and matrix topologies. PXI/PXIe-2527 uses the TB-2627 terminal block; one-, two- and four-wire arrangements require matching wiring.
For selection: Topology, channels, voltage and current, signal type, switch model, terminal block and cables. Example: PXI-2530B part number 778572-30.
USB-6211 and USB-6009 combine analog and digital I/O with different specifications. NI publishes X Series migration guidance for older PXI-6259 and PCI-6221; moving to PXIe or PCIe requires system review.
For selection: Interface, input/output channels, range, per-channel or aggregate rate, operating system and NI-DAQmx version; existing cables and pin assignment.
CompactDAQ combines a chassis with C Series measurement modules. cDAQ-9178 is an eight-slot USB chassis handling synchronization and data transfer between modules and a computer.
For selection: Exact chassis, C Series list, USB/Ethernet requirement, power, synchronization, OS and NI-DAQmx; cable or power-supply needs. Example: cDAQ-9178 part number 781156-01.
NI-9205 measures voltage, NI-9213 handles thermocouples, and NI-9234 measures sound and vibration with IEPE sensor support. Sensor type, excitation, wiring and connector version matter alongside channel count.
For selection: Model and part number, sensor type, channels, range, rate, isolation and connector; exact cDAQ/cRIO model and operating mode.
CompactRIO combines a real-time processor, FPGA and C Series modules. cRIO-9045 supports several programming modes. cRIO-9004 is discontinued; NI lists cRIO-9036 as a migration direction, not a universally interchangeable replacement.
For selection: Controller, chassis and modules, serial number, real-time OS, LabVIEW and driver versions, FPGA/Scan/DAQmx mode; program migration and connection requirements.
PXIe-7976R is a FlexRIO module with a programmable FPGA. Its signal interface also depends on the adapter module, so the FPGA board marking alone does not define the full signal path.
For selection: Exact PXIe-7976R and adapter markings, chassis, connectors, LabVIEW FPGA version and FPGA image; replacement or new signal-path requirements.
GPIB-USB-HS connects IEEE 488 instruments to USB. USB-8486 is for FOUNDATION Fieldbus and uses NI-FBUS. These are different interfaces; check USB-8486 revision, driver version and OS support separately.
For selection: Full model and part number, instrument or network, operating system, driver, cable and mounting; software licences are checked separately.
SCB-68 and SCB-68A bring compatible DAQ signals to screw terminals. The similar-looking SCB-68 HSDIO serves a different function. Match cable and terminal block to module model and pin assignment.
For selection: Both cable endpoints, connector designations, length, shielding, DAQ model and terminal block; existing markings and photos for replacement.
Describe the device under test, signal types and ranges, channel count, measurement rate, synchronization and isolation requirements. Specify connection interface, operating system, drivers and software. For an existing bench, attach the module list and wiring diagram.
Provide the part number and model of each device, marking and connector photos. Cables require pin assignment and connected devices; terminal blocks require compatibility and signal details; modules require chassis and software environment. Package, condition and calibration documents for a particular offer are checked separately.
Include quantity and delivery location. Attach a specification, wiring diagram or marking photo.
