National Instruments USB-6343 Multifunction I/O Device

The National Instruments USB-6343 (Part Numbers: 781439-01, 782253-01, 782252-01, and 150199C-01L) is a Multifunction I/O Device from the X Series. This device has 16 differential (or 32 single-ended) analog input channels, featuring 16 bits of ADC resolution and a maximum sample rate of 500 kS/s. The flexible NI USB-6343 offers simultaneous update rates, which differ depending on the number of channels. The maximum update rate for one channel is 900 kS/s, two channels is 840 kS/s, three channels is 775 kS/s, and four channels is 719 kS/s. 

The analog input channels of the NI USB-6343 multifunction I/O device are safeguarded against damage from overvoltage with protection of ±25 V when the device is powered on. When powered off, it is still protected with ±15 V. These values are sufficient for a maximum of two analog input pins. The USB-6343 from NI also features 4 analog output channels, which come equipped with 16 bits of DAC resolution. These output channels have a maximum sample rate of 500 kS/s, offering high resolution performance for a wide range of applications. 

The various part numbers for the NI USB-6343 differ depending on their connector type. Part number 781439-01 is equipped with screw terminal front connectors, while part number 782253-01 features BNC front connectors. In addition, 782252-01 is the descriptive part number for the board only kit of the multifunction I/O device.

The X Series NI USB-6343 offers DC output coupling and a guaranteed 16 bits of resolution for monotonicity. This device provides 16-bits resolution measurements for monotonicity. The screw terminal I/O connector variation of the device features 128 screw terminals, while the BNC I/O connector version provides 30 BNCS and 60 screw terminals.

Designed only for use indoors, the NI USB-6343 I/O device should be operated in environments where the temperatures range from 0 °C to 45 °C. The device has a storage temperature range of -40 °C to 70 °C. The screw terminal version of the USB-6343 weighs 1.445 kg (3 lb 3 oz) and measures 26.4 cm × 17.3 cm × 3.6 cm (10.4 in. × 6.8 in. × 1.4 in.), while the BNC connector module has a weight of 1.803 kg (3 lb 15.6 oz) and dimensions of 20.3 cm × 18.5 cm × 6.8 cm (8.0 in. × 7.3 in. × 2.7 in.).
