National Instruments 779629-01 PXI Multifunction I/O Module.

The part number 779629-01 from National Instruments is the identifying part number for the PXI-6221 PXI Multifunction I/O Module. This PXI Multifunction I/O Module features 16 analog input channels that can be configured as 8 differential or 16 single-ended inputs. Each channel is equipped with a 16-bit analog-to-digital converter (ADC), ensuring high-resolution signal acquisition. The input ranges are programmable, offering options from -10 V to +10 V to accommodate various signal levels. The maximum sampling rate is 250 KS/s, providing flexibility and high-speed data acquisition. It does not feature simultaneous sampling rate and so cannot sample the data from all channels at the same time, it also features on board memory with 4095 samples.

The 779629-01 PXI Multifunction I/O Module includes 2 analog output channels, each with a 16-bit digital-to-analog converter (DAC). These outputs can generate signals within ranges of -10 V, +10 V, or an external reference range set on APFI 0. The maximum update rate is 833 KS/s, ensuring fast and accurate signal generation. 

The device provides 24 bidirectional digital I/O lines, including 0 input only channels and 0 output only channels. These lines can be individually programmed as inputs or outputs and support static digital I/O operations. The digital I/O lines are TTL compatible and can handle input voltages up to 0 to 5 V and output voltages of up to 0 to 5 V. The 779629-01 PXI Multifunction I/O Module also features 2 bits general-purpose counters/timers capable of performing edge counting, pulse generation, frequency measurement, and more. The counters support various input and output applications, including position measurements using quadrature encoders and pulse train generation. 

The device has length of 16 cm and width of 10 cm. It has a 68-pin female VHDCI I/O connector that makes it suitable for this device to integrate into various digital devices. It operates at a temperature of 0 to 55 degrees Celsius and has a storage temperature of -20 to 70 degrees Celsius with a relative humidity of 10% to 90%, noncondensing.
