National Instruments 9233 simultaneous analog input module for cDAQ / cRIO systems. Tested, fully functional, and in good physical condition with minor surface marks.

Designed for use with IEPE-compatible sensors. Similar to the current 9234 model, but the IEPE excitation is always enabled. See NI application note for details. The 9233 module is supported by NI-DAQmx versions 17.5 and earlier.

Each channel has a BNC connector to which you can connect an Integrated Electronic Piezoelectric (IEPE) sensor. The center pin of the connector, AI+, provides the DC excitation and the AC signal connection. The shell of the connector, AI–, provides the excitation return path and the AC signal ground reference.
