National Instruments PXI-6120 Multifunction I/O Module

The PXI-6120 (Part Number: 778396-01, 187677C-01) is a Multifunction I/O Module, which consists of digital I/O, counter/timer functionality, and analog I/O in one module. This Multifunction I/O Module is well-suited for numerous types of industry applications, including research, design confirmation, and laboratory automation. The NI-DAQmx driver on this module permits the user to fully tailor automation and measurement applications from many supported programming languages. API support is also included for LabVIEW and text-based languages, along with shipping samples and informative help documents. The PXI-6120 Multifunction I/O Module has four input channels, two output channels, eight DIO channels, and two counter channels, as well as a sample rate of 1 MS/s and 16-bit resolution.

The National Instruments PXI-6120 comes equipped with analog signal paths that have been carefully created, assessed, and calibrated to guarantee the utmost preciseness for every input channel. The 100 MHz timebase is nearly five times quicker than previous models. Therefore, sampling frequencies are almost five times more exact, allowing analog triggers to react within 10 ns of a trigger setting being met. This Multifunction I/O Module has a phase locking feature, which enables numerous instruments to be synchronized to one PXI backplane clock to preserve the phase between measurements across numerous instruments analog input channels.

Analog input, analog output, and general-purpose counter/timer functions can all be independently configured with NI's multifunction I/O technology. This is contrasted by digital I/O operations, which are timed by relating with other internal or external sample clocks instead of their own dedicated internal clock. One example is that retriggerable acquisitions consist of waiting for a trigger setting to be met, taking a certain amount of samples, then instantaneously rearming the trigger for the following acquisition. Utilizing driver software function calls to rearm the trigger means the possibility of skipping the following trigger because of software dormancy, so the highest performance demands a hardware-timed method. The PXI-6120 is equipped with a 68-pin male SCSI-II type I/O connector. The NI device measures 6.3 x 3.9 in. in physical dimensions. It has recommended operating and storage temperature ranges of 0 °C to 50 °C and -20 °C to 70 °C respectively.

Apex Waves will continue to Buy, Sell, and Repair EOL NI Hardware in perpetuity. While the PXI-6120 is no longer available from National Instruments, the Multifunction I/O Module will remain available with us. Request your quote today!
