Description
The National Instruments PXI-6225 Multifunction I/O Module, part number 779296-01, is a versatile component of the M Series that offers 40 differential or 80 single-ended analog input channels with a 16-bit resolution and a maximum sampling rate of 250 kS/s. It also provides two analog output channels and 24 digital I/O/PFI channels, facilitating a wide range of data acquisition tasks.
The module features two 68-pin VHDCI I/O connectors and supports various input signal modes, including referenced single-ended, differential, and non-referenced single-ended, making it highly adaptable to different signal types. The integrated NI-PGIA instrumentation amplifier ensures precise measurements, and the module is compatible with floating signal sources such as optical isolators, thermocouples, isolation amplifiers, transformers, and battery-powered devices.
For optimal performance, the PXI-6225 requires a warm-up time of 15 minutes and should undergo calibration at least once a year. It is lightweight at just 6.1 ounces and operates reliably within a temperature range of 0 °C to 55 °C, making it suitable for various industrial environments.
