National Instruments 779680-01 4-channel, 24-bit Dynamic Signal Acquisition Module

The National Instruments 779680-01, also known as the NI 9234 C Series Sound and Vibration Input Module, is a specialized data acquisition device designed for measuring acoustic and vibrational signals in industrial and laboratory environments.

The NI 9234 is a 4-channel, 24-bit dynamic signal acquisition module optimized for sound and vibration measurements. It is compatible with CompactDAQ or CompactRIO systems, enabling integration into modular test and measurement setups. This module supports both IEPE (Integrated Electronic Piezoelectric) and non-IEPE sensors, such as accelerometers, microphones, tachometers, and proximity probes, making it suitable for applications like machinery diagnostics, structural analysis, and audio testing.
