NI SCXI-1104C 32-Channel Analog Input Signal Conditioning Module

NI SCXI-1104C is a 32-channel differential analog input signal conditioning module from National Instruments SCXI platform. It is designed for medium voltage signal acquisition, with built-in 10:1 attenuator and 10kHz low-pass filter to process industrial voltage signals before sending to DAQ hardware.

This module multiplexes 32 input channels into a single analog output channel, compatible with NI SCXI chassis and various DAQ cards. It serves as a spare part for laboratory measurement, industrial test bench and power monitoring data acquisition system maintenance and upgrade projects.
