National Instruments PXI-6251

The National Instruments PXI-6251 is a versatile PXI Multifunction I/O Module designed to fulfill a wide range of applications, including manufacturing test, research, laboratory automation, and design verification. This module features 8 differential or 16 single-ended analog input channels with a 16-bit resolution, two analog output channels, and 24 digital I/O channels. It is engineered to be complementary with signal conditioning modules, such as SCXI or SCC, to accommodate high-voltage and sensor features. The PXI-6251 utilizes a 68-pin VHDCI I/O connector and can be connected via a 2 m shielded SHC68-68-EPM cable along with an SCB-68 Spring-Screw Terminal Connector Block. Importantly, the PXI-6251 is designed to work exclusively with the NI-DAQmx driver software, offering enhanced capabilities like automatic timing, triggering, and synchronization for efficient application development. NI-DAQmx also supports a consistent programming interface across analog output, analog input, and digital I/O channels, ensuring optimal performance and ease of use. The module has a warm-up time of 15 minutes and should be calibrated at least once every two years. Operating within a temperature range of 0 ºC to 55 ºC, the standard 3U PXI device weighs 7.8 ounces and includes a three-year warranty.
