Product Description

The PXI-6229 is a workhorse in the PXI platform, offering a high channel count for analog input, analog output, and digital I/O. It utilizes the NI-STC2 system controller, which provides advanced timing and synchronization features, including independent timing engines for different I/O types.

Product Parameters

The PXI-6229 is optimized for high-density requirements where multiple signal types must be managed by a single slot.

Product Advantages

• High Channel Density: With 32 AI and 48 DIO lines, it provides one of the highest I/O densities available in a single PXI slot, reducing the overall system footprint.

• M Series Accuracy: Features the NI-PGIA 2 amplifier technology, which minimizes settling times even at high sampling rates, ensuring data integrity when scanning multiple channels.

• Hardware-Timed Digital I/O: Unlike basic digital cards, the PXI-6229 supports hardware-timed digital lines, allowing for precise synchronization between digital patterns and analog signals.

• Cost-Effective: Part of the “M Series,” it offers a lower price point than the high-speed X Series (like the 6363) while still maintaining 16-bit resolution.

• NI-DAQmx Compatibility: Seamlessly integrates with LabVIEW, Python, and C, significantly reducing development time.

Key Considerations (Precautions)

• Aggregate Sampling Rate: The 250 kS/s rate is aggregate. This means if you are sampling 10 channels, each channel will have a maximum rate of 25 kS/s.

• VHDCI Cabling: The 48 digital lines and 32 analog inputs are distributed across two 68-pin VHDCI connectors. You will likely need two cables (SHC68-68-EPM) and two connector blocks (such as the SCB-68) to access all I/O.

• PXI vs. PXIe: This is a PXI (Standard) module. While it will fit into “Hybrid” slots of a PXI Express chassis, it cannot utilize the high-speed PXIe backplane features.

• Signal Noise: Because of the high density, careful attention must be paid to cable shielding to prevent crosstalk between the 48 digital lines and the sensitive analog inputs.

Product Applications

1. Manufacturing Test: Ideal for testing consumer electronics where a mix of power monitoring (AI), control signaling (AO), and state checking (DIO) is required.

2. Environmental Monitoring: Logging data from a large array of sensors (thermocouples via signal conditioning, pressure transducers, etc.).

3. Laboratory Automation: Controlling small-scale chemical or physical experiments that require precise timing and multiple I/O points.

4. Legacy System Maintenance: Replacing older DAQ cards in existing PXI test stands without needing to rewrite complex NI-DAQmx code.
