NI Hardware sale

Used NI Hardware for sale

As a NI partner we use a lot of NI harware in our projects. From some older projects we have some of this hardware still on the shelf. Now, with the shortages of chips and long lead-times for new hardware we decided to put some parts on sale in order to hopefully help businesses to build their systems faster.

All items listed below are in stock at our Netherlands office. If you're interested in one or more items just drop us an e-mail at and we'll send you a quote ASAP. Please note that these products are all fully functional, but not new and come without any warranty.


NI PXI-4071 (sold)

7½-Digit, ±1,000 V, Onboard 1.8 MS/s Isolated Digitizer, PXI Digital Multimeter

The PXI‑4071 is a high-performance 7½‑digit, 1,000 V DMM that provides the measurement capabilities found in two common test instruments: a high-resolution DMM and a digitizer. As a DMM, the PXI‑4071 delivers fast, accurate AC/DC voltage, AC/DC current, 2‑ or 4‑wire resistance, and frequency/period measurements, as well as diode tests. In the high-voltage, isolated digitizer mode, the PXI‑4071 can acquire waveforms at sample rates up to 1.8 MS/s.

NI USB-8451

I²C/SPI Interface Device (New in box but out of warranty)

250 kHz I2C, 12 MHz SPI I2C/SPI Interface Device

The NI USB‑8451 is a master interface for connecting to and communicating with inter-integrated circuit (I2C), System Management Bus (SMBus), and serial peripheral interface (SPI) devices. With plug‑and‑play USB connectivity, the USB‑8451 is a portable solution to communicate with consumer electronics and integrated circuits. It also includes eight general-purpose digital I/O lines for a variety of applications, such as configuring the address of I2C devices or toggling LEDs. The USB‑8451 can be physically located more closely to I2C/SPI devices than PCI interfaces, reducing I2C bus length and minimizing noise problems. Additionally, the interface provides +5 V and GND to power circuits with no external power supply.

NI 9435

C-Series Digital input module

±5 VDC to ±250 VDC/10 VAC to 250 VAC, 4-Channel (Sinking/Sourcing Input), 3 ms C Series Digital Module

The NI‑9435 works with industrial logic levels and signals to connect directly to a wide array of industrial switches, transducers, and devices. Each channel accepts signals from ±5 VDC to ±250 VDC and 10 VAC to 250 VAC; features transient overvoltage protection between the input channels and earth ground; and has an LED that indicates the status. The NI‑9435 is a correlated digital module, so it can perform correlated operations, triggering, and synchronization when installed in a CompactDAQ chassis.

NI 9481

C-Series Relay output module

4-Channel, SPST Relay, 60 VDC(1 A)/ 250 Vrms (2 A) C Series Relay Output Module

The NI‑9481 directly connects to a wide array of industrial devices such as motors, actuators, and DC devices. Each channel provides access to an electromechanical relay for switching signals up to 60 VDC (1 A) or 250 Vrms (2 A), features channel-to-channel isolation, and has a LED that indicates the status. The shock and vibration rating for the NI‑9481 is limited compared with other CompactDAQ and CompactRIO modules because of the mechanical relays on the module.
