National Instruments PC-516

The National Instruments PC-516 Multifunction I/O Module is a cost-effective solution designed for versatile input/output applications. It supports 8 single-ended analog input channels, which can be configured as 4 differential channels through software, achieving a maximum sampling rate of 50 kS/s with 16-bit resolution. The onboard analog-to-digital converter (ADC) delivers a signal resolution of 152 μV across a ±5 V voltage range. Additionally, the module features 8 digital I/O terminals that are TTL-compatible with 5 V logic levels. Built with overvoltage protection of ±25 V for input circuitry, the PC-516 ensures reliable operation in diverse environments. It is compatible with Windows operating systems including NT, 2000, and 9x, and integrates seamlessly with NI-DAQ driver software as well as application development environments such as LabVIEW and LabWindows/CVI. The module is equipped with two 10 MHz timers, a FIFO buffer capable of holding 512 samples, and requires a stability time of 15 minutes post-activation for optimal performance. The PC-516 is housed in a compact 4.25 by 4.3-inch form factor and connects via a 27-pin male I/O connector. Operating temperature is specified between 0-55 °C and boasts a high input impedance of 10 GΩ with 20 pF parallel capacitance. The product is backed by a 2-3 year warranty, with user and maintenance manuals available for download. For pricing information, please contact a sales representative.
