NI SCXI-1100 32-Channel Analog Input Signal Conditioning Module

The NI SCXI-1100 is a 32-channel analog input signal conditioning module belonging to the SCXI measurement platform. It supports both differential and single-ended signal access, with programmable gain and jumper-selectable low-pass filters for millivolt, voltage and current sensor signal preprocessing.

This legacy DAQ module needs to work with SCXI chassis and NI DAQ acquisition cards. It is commonly used as spare replacement for aging multi-channel test benches, laboratory measurement systems and industrial process data acquisition equipment.
