National Instruments has added four C Series modules for data-logging applications including vibration/acoustical data logging and in-vehicle, structural, temperature and pressure testing.

The NI USB-9219, USB-9229 and USB-9239 provide USB, bus-powered connectivity to the C Series while the NI 9234 AC/DC-coupled dynamic signal acquisition module offers selectable IEPE signal conditioning for engineers measuring high-accuracy audio frequency.

There are more than 40 C Series modules available for different measurements including thermocouple, voltage, current, resistance and strain.

The bus-powered USB-9219, USB-9229 and USB-9239 four-channel universal modules are designed for multipurpose testing in CompactDAQ or CompactRIO chassis, or with the USB-9162 single module carrier.
