The National Instruments PCI-6143 Multifunction I/O Device, identified by part number 778913-01, is designed for versatile data acquisition and control applications. This module features eight differential analog input channels, each equipped with a 16-bit resolution ADC that provides high-precision signal representation. It supports a maximum sampling rate of 250 kS/s, accommodating a broad spectrum of measurement requirements with an input range of ±5 V and DC input coupling. The device is capable of handling data with an input FIFO size of 2,046 samples and utilizes flexible data transfer methods including DMA, interrupts, and programmed I/O, ensuring efficient data management.

In addition to analog inputs, the PCI-6143 includes two 24-bit counters that facilitate various measurements such as edge counting, period, pulse width, and two-edge separation, further expanding its utility in timing applications. The base clock operates at 20 MHz with an impressive accuracy of ±0.01%. The device is equipped with eight digital I/O channels that can be configured for individual input or output operations, enhancing its adaptability for diverse digital control tasks.

Connectivity is facilitated through a 68-pin VHDCI connector, supporting a wide array of signal conditioning accessories for seamless integration into measurement setups. The PCI-6143 is optimized for use within a standard PCI bus environment, operating efficiently while consuming 40 mA at +5 VDC, 140 mA at +3.3 VDC, 150 mA at +12 VDC, and 80 mA at -12 VDC. Physical dimensions measure 15.5 cm by 10.6 cm (6.10 in. by 4.17 in.), and the device is suited for indoor use with an operating temperature range of 0°C to 50°C and a storage temperature range of -20°C to 70°C. It supports operating humidity levels of 10% to 90% (noncondensing) and storage humidity levels of 5% to 95% (noncondensing), and is designed for operation up to an altitude of 2000 meters, making it a reliable choice for a multitude of industrial applications.
