National Instruments 779624-01 Bank-Isolated Multifunction I/O Module

National Instruments part number 779624-01 is an identifying part number for the PXI-6238 Multifunction I/O Module. The 779624-01 features bank isolation and 16 analog inputs that are each equipped with 16 bits of resolution and a rate of 1.25 MS/s. In addition, the module is equipped with 2 analog outputs, 6 digital inputs, and 4 digital outputs.

This module can auto-calibrate to correct displacement and adjust errors. Additionally, users can align the device to minimize analog input errors caused by time and temperature drift during operation. No external circuit is necessary for this module; an internal reference ensures high accuracy stability over time and through temperature changes. It features 8 differential current input channels, each with a ground reference (AI GND) and a 16-bit ADC resolution, accommodating an input range of ±20 mA. Additionally, the module includes 2 current output channels, each with a 16-bit DAC resolution. In this model, sensors can generate electrical signals to measure physical aspects like temperature, force, sound, or light.

Commonly used sensors include strain gauges, thermocouples, thermistors, angular encoders, linear encoders, and resistance temperature detectors (RTDs). The 779624-01 comes with two counter/timers with a resolution of 32 bits. It supports a variety of output applications, including pulse generation, pulse trains with dynamic updates, frequency division, and equivalent time sampling. Data transfers are handled by a dedicated scatter-gather DMA controller for each counter/timer and can also be managed through interrupts and programmed I/O.
