National Instruments 781005-01 Multifunction I/O Device.

The part number 781005-01 from National Instruments is the identifying part number for the USB-6218 Multifunction I/O Device. This multifunction I/O module by the national instrument features 16 differential or 32 single ended input channels, each with a 16-bit analog-to-digital converter (ADC). The device supports a maximum single channel sample rate of 250 kS/s and a multichannel maximum sampling rate of 250 kS/s, which is ideal for capturing fast transient signals. The input range is adjustable, offering ±0.2 V, ±1 V, ±5 V, ±10 V to accommodate various signal levels. The device ensures high input impedance less than 10 GΩ in parallel with 100 pF when powered on and 1200 Ω when powered off with an input bias current of 100 pA.

The Multifunction I/O Module also includes 2 analog output channels with 16-bit DAC resolution, capable of generating signals at a maximum update rate of 250 kS/s per channel and it also offers a timing accuracy of 50 ppm of sample rate with timing resolution of 50 ns. The output range is configurable up to ±10 V, providing versatility for signal generation tasks. 

The output channels have a low output impedance of 0.2 Ω and can drive currents up to ±2 mA. It also have overdrive protection voltage of ±30 V with an over drive current of 2.4 mA, thus protecting the module from damage by excessive input signals and current levels. It has output FIFO memory size of 8,191 samples with a data transfer method of USB Signal Stream and programmed I/O.

This Multifunction I/O Module is designed for reliable operation in various environments. It operates within a temperature range of 0 degrees Celsius to 45 degrees Celsius and can be stored between -20 degrees Celsius to 70 degrees Celsius. The device has a relative humidity 10% to 90% RH, noncondensing and can be mounted at height of 2000 meters with a pollution degree of 2. Its physical dimensions are 23.5 cm × 11.2 cm × 6.4 cm(9.25 in. × 4.40 in. × 2.50 in.) with the BNC connector and 16.9 cm × 9.4 cm × 3.1 cm (6.65 in. × 3.70 in. × 1.20 in.) with the screw terminal connector. It weighs approximately 950 g (33.5 oz) with the BNC connector and 206 g (7.2 oz) with the screw terminal connector.
