The National Instruments 777740-01 is a High-Speed Voltage Output Module, specifically identified as the PCI-6711. This module is designed with four analog output channels capable of delivering a voltage range of ±10 Volts. It features a maximum output impedance of 0.1 Ω, which ensures stable voltage output across varying loads while minimizing heat dissipation, thus enhancing the module's efficiency and lifespan. Each output channel supports a strong current drive of 5 milliamps, facilitating robust performance in demanding applications. The 777740-01 includes advanced protection features, such as short-circuit protection to ground, enabling reliable operation in challenging environments. Its output stability accommodates passive loads up to 1,500 pF, making it well-suited for high-performance tasks. The module supports high update rates of up to 1 MS/s per channel through local FIFO memory, utilizing an 8,192 sample FIFO buffer size to support fast voltage generation and real-time control applications. It employs a double-buffered, multiplying digital-to-analog converter (DAC) for smooth voltage transitions and features scatter-gather DMA, which streamlines data processing for applications with high data throughput requirements. With compact dimensions of 17.5 cm × 10.7 cm (6.87 × 4.2 inches) and a weight ranging from 100 to 200 grams, the module is equipped with a 68-pin male SCSI-II input/output connector for easy integration. It operates at a +5 VDC power supply with a current draw of 0.80 A and is designed to function in ambient temperatures from 0 to 50 degrees Celsius, with a storage range of -20 to 70 degrees Celsius and humidity levels of 5% to 90% RH, non-condensing. The module can be installed at altitudes up to 2000 meters and adheres to industry standards including IEC 61010-1, EN 61010-1, UL 61010-1, and CSA 61010-1. The PCI-6711 module is a versatile solution for applications requiring precise voltage output and high-speed data processing.
