National Instruments 779373-01 C Series Voltage Input Module

The National Instruments part number 779373-01 from is the identifying part number for the NI-9221 C Series Voltage Input Module. It features 8 voltage input channels with an successive approximation register (SAR) analog to digital convertor of 12 bit resolution. Its maximum sample rate for the R series expansion chassis is 475 kS/ per second while for the other chassis it has 800 kS per second. This module offers voltage input range of ±60 V and a typical voltage of ±62.50 V and a maximum of ±63.8 V for channel to COM.

The power requirements for thie 779373-01 is 1 W maximum in active mode and 1 mW maximum in sleep mode drawing these power from the chassis while the power dissipated at 70 degrees Celsius is 1 W maximum at active mode and 32 mW maximum at sleep mode. This module features both screw terminal wiring and spring terminal wiring. For the screw terminal wiring, its gauge is 0.2 mm^2 to 2.5 mm^2 with a temperature rating of 90 degrees Celsius minimum. The wire must be stripped from the end with a length of 13 mm. This module weighs 165 g with screw terminal wiring and 152 g with spring terminal wiring.

This 779373-01 C Series Voltage Input Module is designed to operate at an ambient temperature of -40 degrees Celsius to 70 degrees Celsius with operating humidity of 10% RH to 90% RH, noncondensing and storage temperature of -40 degrees Celsius to 85 degrees Celsius with a storage humidity level of 5% RH to 95% RH, noncondensing. This module includes ingress protection of rating IP40 which means that it is protected from dust and moisture. It can be mounted at maximum height of 2000 meters with a pollution degree of 2.

In terms of vibration and shocks, the operating shocks for the 779373-01are 30 g, 11 ms half sine, 50 g, 3 ms half sine, 18 shocks at 6 orientations and it has random vibrations of 5 g RMS, 10 Hz to 500 Hz and sinusoidal vibration of 5 g, 10 Hz to 500 Hz, with these specification it is able to work under harsh condition.
