National Instruments 781441-01 Multifunction I/O Device

The National Instruments part number 781441-01 from is the identifying part number for the USB-6353 Multifunction I/O Device. The device comprises 16 differential or 32 single ended analog input channels with a 16 bit ADC resolution. It features a single-channel maximum sampling rate of 1.25 MS per second and a multi channel maximum sample rate of 1.00 MS per second with no minimum sample rate. It offers various input voltage ranges of ±0.1 V, ±0.2 V, ±0.5 V, ±1 V, ±2 V, ±5 V, and ±10 V with a maximum working voltage of ±11 V. Its input impedance is less than 10 GΩ in parallel with 100 pF when the device is ON while 820 Ω when the device is OFF.

The 781441-01 Multifunction I/O Module includes 4 analog output channels with a 16 bit DAC resolution that is capable of generating signals at a maximum update rate of 2.86 MS per second on one channel, 2.00 MS per second on two channel, 1.54 MS per second on three channel and 1.25 MS per second on four channel and it also offers timing accuracy of 50 ppm of sample rate with a timing resolution of 10 ns. These output channels have a low output impedance of 0.2 Ω and an output current drive of ±5 mA. It has an overdrive protective feature that can protect up to ±25 V and 26 mA of overdrive current.

To operate this module, 11 to 30 VDC of power is required, and is equipped with a 3.5 mm pitch pluggable screw terminal with screw locks. Its physical dimensions are 26.4 cm × 17.3 cm × 3.6 cm (10.4 × 6.8 × 1.4 in.) with an enclosure and it weighs 1.42 kg (3 lb 2 oz). This module comes with a 128 screw terminal I/O connector.

The 781441-01 Multifunction I/O Module is designed to operate at a temperature of 0 to 45 degrees Celsius with operating humidity of 10% to 90% RH, noncondensing, and storage temperature of -40 to 70 degrees Celsius with storage humidity of 5% to 95% RH, noncondensing.
