Key product information and technical features.
The PCI-6232 combines voltage acquisition, analog output, digital I/O, and counter/timer functions on a PCI card. Its bank-isolated architecture separates signal groups rather than providing independent isolation for every analog channel.
Analog input bandwidth is shared across the acquisition scan: the 250 kS/s rating is aggregate, not a per-channel rate. The NI 6232/6233 User Manual explains channel timing, signal connections, triggering, and synchronization.
