National Instruments 779182-01 Analog Input Module 

The National Instruments part number 779182-01 corresponds to the PXI-4224, an Analog Input Module. This module features 8 differential analog input channels with a resolution of 16 bits. It supports a maximum input voltage range of ±10 VDC and can achieve a sampling rate of up to 200 kS/s. The 779182-01 offers channel-to-channel isolation and integrated signal conditioning, which ensures precise and safe measurements, even when dealing with high common-mode voltages. This makes it suitable for applications like isolated thermocouple measurements, multichannel data logging, and testing fuel cells and batteries.

The module provides 60 VDC (42 Vrms) CAT I isolation between channels and allows programmable gain settings per channel, optimizing measurement accuracy. The included NI-DAQmx driver software streamlines hardware setup and automates the measurement process. For connecting signals to the NI 779182-01, you can use the TB-2725 terminal block or a 25-pin D-SUB for custom connections. When connecting a ground-referenced signal source, connect the signal (V+) to the 779182-01 channel input (AI X +) and the signal reference (V–) to the channel reference (AI X –). This setup, similar to a standard ground-referenced signal connection, also benefits from shielding around the wiring to minimize noise from capacitive or electrical coupling.

Using the NI-DAQmx software, there is a specific function that modifies the internal and external calibration constants of the SCMP pod on the 779182-01. This function is DAQmxAdjust4224Cal, but it is important to note that this requires a known voltage to be indicated using inputVal.

National Instruments has marked the 779182-01 as obsolete, but it remains available for purchase or for repair services from Apex Waves.
