Description
NI PXI-8820 PXI Controller Module
The NI PXI-8820 is a high-value, high-performance embedded controller from National Instruments (NI). It is designed for use in PXI and PXI Express systems, offering a compact and ruggedized PC-based platform for automated test, measurement, and control applications.
Product Detailed Description
The PXI-8820 is a 2-slot embedded controller that fits into any PXI Express or PXI hybrid chassis. It features an Intel Celeron T3100 dual-core processor. By integrating the controller directly into the PXI chassis, it eliminates the need for an external PC and high-latency cables, providing a high-bandwidth connection to the instrumentation modules via the PXI backplane.
Technical Parameters
| Feature | Specification |
| Processor | Intel Celeron T3100 (Dual-Core, 1.9 GHz) |
| Memory (RAM) | 2 GB DDR3 (standard), upgradeable up to 4 GB |
| Hard Drive | 250 GB (or larger) SATA HDD or SSD |
| System Bandwidth | Up to 1 GB/s |
| I/O Ports | 1x Gigabit Ethernet, 4x USB 2.0, 1x Parallel, 1x RS-232 |
| Video Output | VGA (supports up to 2048 x 1536) |
| Operating System | Windows 7 (standard) or LabVIEW Real-Time |
| Slot Occupancy | 2 PXI Express slots |
Product Advantages
- Cost-Effectiveness: Provides a dual-core processing solution at a lower price point than the high-end PXIe-8840 or 8880 series, making it ideal for budget-conscious production testing.
- Compact Integration: Its 2-slot design leaves more space in the chassis for additional measurement and signal generation modules.
- High Reliability: Designed for 24/7 industrial operation; unlike a consumer laptop, it features better cooling and a more rigid mechanical structure to withstand vibration.
- Universal Compatibility: Works with both PXI and PXI Express peripheral modules, allowing you to mix legacy and modern instrumentation.
Important Considerations (Precautions)
- Chassis Compatibility: Ensure your chassis has a “Controller Slot” (Slot 1) that supports the physical dimensions and backplane pins of the PXI-8820.
- Thermal Management: Do not block the air intake on the front of the controller. Ensure the chassis fans are operational, as embedded controllers can generate significant heat during intensive processing.
- Memory Limits: While 2 GB is standard, modern Windows-based applications may require an upgrade to 4 GB for optimal performance.
- Storage Life: If used in a high-vibration environment, consider replacing the standard HDD with a Solid State Drive (SSD) to prevent mechanical failure.
Product Applications
- Automated Production Test: Running LabVIEW or TestStand sequences to validate electronic components on a manufacturing line.
- Data Acquisition (DAQ): Managing high-speed data streaming from multiple analog-to-digital converter modules.
- Industrial Control: Serving as a localized controller for complex machinery where real-time determinism (using LabVIEW RT) is required.
- Education & Research: Used in university laboratories for signal processing, RF measurements, and physics experiments.
