The NI PXI-6040E is a multi-function data acquisition (DAQ) module developed by National Instruments (NI), USA. Below is its comprehensive introduction:
1. Basic Information
- Module Series: Belongs to the E-Series, compatible with both PCI and PXI buses.
- Physical Dimensions: Approximately 160mm × 99mm.
2. Technical Specifications
Analog Input
- Channel Configuration: 16 single-ended channels or 8 differential channels.
- Sampling Rate: Up to 500kS/s (single-channel mode); 250kS/s (multi-channel mode).
- Input Range: Switchable across multiple ranges, from ±0.05V to ±10V.
Analog Output
- Channel Count: Up to 2 channels with 12-bit resolution.
- Output Range: Matches the analog input range, suitable for waveform generation or process control.
Digital I/O
- I/O Lines: 8 digital I/O lines, applicable for external device control or status monitoring.
Counter/Timer
- Configuration: 2 channels of 24-bit counters/timers.
- Supported Functions: Pulse width measurement, frequency analysis, and other timing-related tasks.
Synchronization & Triggering
- Supports analog triggering for synchronized data acquisition with other modules.
- The PXI version enables backplane trigger routing (via the PXI chassis) to achieve multi-device synchronization.
3. Software Support
- Compatible with the NI-DAQ driver software.
- Operating System Compatibility: Windows 2000/NT/Me/9x and MacOS.
- Seamless integration with NI software tools such as LabVIEW and TestStand.
- Also supports other development environments, including LabWindows/CVI and Measurement Studio.
4. Typical Application Scenarios
- Mechanical monitoring and image processing
- Scientific research and education
Specific use cases include: electronic component testing, production line monitoring, sensor signal acquisition, product defect detection, signal analysis, and control system design.
5. Selection Recommendations
- For multi-device synchronization requirements, prioritize the PXI version.
- For standalone operation, choose the PCI version to reduce costs.
- The PXI-6040E offers excellent cost-effectiveness for scenarios with moderate sampling rate demands (<250kS/s). For applications requiring higher sampling rates or resolution, consider NI’s S-Series or X-Series modules.
