Product Description & Procurement Process

National Instruments: NI 9234 Sound and Vibration Input Module

The NI 9234 is a high-performance, 4-channel dynamic signal acquisition module designed for making high-accuracy measurements from accelerometers, tachometers, and microphones. Whether you are performing modal analysis on a bridge or measuring the acoustic profile of a turbine, the NI 9234 delivers the precision and dynamic range (102 dB) required to capture subtle signals in noisy industrial environments.

Compatible with both CompactDAQ and CompactRIO chassis, this module features integrated IEPE (Integrated Electronic Piezoelectric) signal conditioning. It provides the necessary constant current to power your sensors, simplifying wiring and reducing the need for external signal conditioners.

Frequently Asked Questions (FAQ)

Q1: Does the NI 9234 work with both cDAQ and cRIO?

A: Yes. The NI 9234 is a standard C Series module. It can be used in a CompactDAQ chassis for USB/Ethernet data logging or in a CompactRIO chassis for real-time FPGA-based monitoring.

Q2: Can I use this with standard 3-wire accelerometers?

A: The NI 9234 is specifically designed for 2-wire IEPE (or ICP®) sensors. If you have a different sensor type, please contact us for a technical compatibility check.

Q3: How do I configure the IEPE and Coupling settings?

A: These settings are software-configurable via NI-DAQmx or LabVIEW. You do not need to move any physical jumpers on the module.

Q4: How fast is shipping to industrial zones in the Middle East?

A: We maintain ready-to-ship stock. Express air freight (DHL/FedEx) typically takes 3–5 business days to reach major industrial hubs like Dammam, Riyadh, or Almaty.
