Products Description
NI SCXI-1102 32-Channel Input Conditioning Module in stock
NI SCXI-1102 is National Instruments SCXI signal conditioning module with 32 differential analog input channels, designed for thermocouple, millivolt and low-level voltage signal measurement. It integrates low-pass filter and programmable gain amplifier, multiplexing multiple input signals to one output channel for DAQ hardware acquisition.

This module has built-in cold junction sensor for thermocouple temperature compensation. It supports gain selection of 1 or 100, equipped with 2Hz low-pass filter to suppress power frequency noise. It is installed in SCXI chassis, widely used for industrial temperature test and low voltage signal data acquisition systems.
