National Instruments PCI-8516

The National Instruments PCI-8516 is a high-performance LIN interface device designed for use in soft-motion control applications. With part number 781365-01, this PCI-bus interface board features two ports capable of supporting data rates up to 20 kbit/s and is equipped with robust ATMEL ATA6620 transceivers. The PCI-8516 excels in versatile applications ranging from compact medical devices to large-scale earth-moving equipment. It offers six channels for enhanced encoder interfacing, along with a 16-bit D/A output supporting both position mode servo drives and stepper drives. The device processes A and B phase signals at frequencies of up to 5 MHz while isolating the encoder and D/A interfaces from potential short circuits or broken wire scenarios. Additionally, advanced features such as low-speed feedback subcounting, watchdog alerts for encoder wire failures, and digital input/output configurations for precise position locking and CAM analysis ensure reliable performance. The highly integrated design includes support for various physical layers optimized for different standards, enhancing flexibility within various applications. The NI-XNET driver allows seamless integration with programming environments like LabVIEW, LabWindows/CVI, and C/C++, while its built-in DMA engine minimizes messaging latency for superior signal processing. Operating temperature ranges from 0 °C to 55 °C, with power requirements of +3.3 VDC at 940 mA, and the device dimensions measure 4.2 in. x 6.6 in. (10.67 cm x 16.76 cm), weighing 3.6 oz. (102 g). For comprehensive use, user manuals are readily available for download, and support is provided under a warranty of 2 to 3 years. For pricing information, please contact a sales representative.
