PCI-1741U and PCI-1742U are powerful high-resolution multifunction data acquisition cards supporting universal PCI bus. The sampling rate is up to 1 MS/s (PCI-1742U) or 200 kS/s (PCI-1741U). Coupled with the 16-bit A/D converter, they are suitable for most data acquisition applications. PCI-1741U and PCI-1742U provides 16 single-ended or 8 differential analog input channels and 16 digital input/output channels. PCI-1741U provides one 16-bit D/A output channel, while PCI-1742U provides two 16-bit D/A output channels.
