The NI PCI-6289 is a multifunction data acquisition module delivering 32 single-ended (or 16 differential) analog input channels, 4 analog output channels, 48 digital I/O lines, and 4 counter/timers on a single PCI board. Operating at 1 MS/s aggregate sampling with 16-bit resolution and dual ADCs for simultaneous multi-channel acquisition, it serves demanding measurement and control applications across laboratory, industrial, and system integration environments.
