The National Instruments PCI-6731 (Part Number: 778511-01) is a high-performance 4-channel, 16-bit analog output device designed for parallel multichannel updates in stimulus-response testing and simulation applications, including acoustic distortion and three-phase power simulation. With a sampling rate of 1 MS/s, the PCI-6731 ensures precise output for various applications and serves as a cost-effective alternative to traditional instruments such as PID controllers and function generators. This PCI-based board features 8 TTL/CMOS-compatible digital I/O lines and two 24-bit counter/timers operating at a frequency of 20 MHz, allowing for a wide range of digital input and output applications, including device state sensing and TTL signal reception.

The device supports external clocking and digital triggering, facilitating both continuous and finite pulse generation. It is equipped with a 68-pin male SCSI-II I/O connector for seamless integration into existing systems. Each line on the PCI-6731 defaults to high-impedance inputs upon startup, and includes weak pull-up resistors, which enhances its usability in various configurations. Operating temperature ranges from 0 to 50 °C, with storage capabilities between -20 to 70 °C and non-condensing humidity from 5 to 90% RH, ensuring the device functions reliably under diverse environmental conditions.

The PCI-6731 is compatible with NI-DAQmx driver software and can be configured via the Measurement & Automation Explorer (MAX) tool, making it ideal for integration with popular software development environments such as LabVIEW, LabWindows/CVI, and Measurement Studio. Its dimensions are 6.87 x 4.2 inches, and it is backed by a three-year warranty. For operational guidance and specifications, user and maintenance manuals are available for download.
