Description
Product Overview: NI PCIe-1427 High-Speed Image Acquisition Card
The NI PCIe-1427 is a high-performance image acquisition card developed by National Instruments (NI) for advanced machine vision and high-speed imaging applications. Designed to leverage the bandwidth of the PCI Express (PCIe) interface, this card enables rapid transfer and processing of image data from high-resolution cameras, making it ideal for real-time inspection, motion analysis, and scientific imaging. With support for Camera Link standards, the PCIe-1427 ensures seamless integration with industrial cameras while providing robust software tools for development and deployment.
Key Features & Benefits
High-Speed Data Transfer:
Utilizes a PCIe x4 Gen 2 interface to achieve data rates up to 6.8 Gb/s, minimizing latency and enabling real-time processing of high-resolution image streams.
Camera Link Compatibility:
Supports Base, Medium, Full, and 80-bit Deca Camera Link configurations, providing flexibility to interface with a wide range of industrial cameras.
Onboard Memory and Processing:
Features 512 MB of onboard DDR2 memory for buffering large image datasets, reducing host CPU load and ensuring stable performance during continuous acquisition.
Hardware Triggering and Synchronization:
Includes multiple I/O lines for precise hardware triggering, strobe control, and synchronization with external devices (e.g., encoders, sensors), critical for high-speed automation.
Software Integration:
Fully compatible with NI Vision Development Module and LabVIEW, allowing users to develop custom vision algorithms with drag-and-drop tools and pre-built libraries.
Multi-Camera Support:
Capable of hosting two independent Camera Link ports (via adapter), enabling simultaneous acquisition from multiple cameras for complex vision systems.
