The PCI-826LU is a high performance multifunction card providing high-speed analog I/O and digital I/O functions. The PCI-826LU card has a universal PCI interface supporting both 3.3 V and 5 V PCI bus. This card features a continuous, 250 k Samples/Sec 16-bit resolution A/D converter, 8 K samples hardware FIFO, 2-ch 16-bit D/A converter, 32-ch programmable digital I/O and DO read back.The PCI-826LU provides either 32-ch single-ended or 16-ch differential analog inputs which are jumper selectable. The PCI-826LU is equipped with a high speed PGA featuring programmable gain controls (1, 2, 4, 8).
The PCI-826LU has the Card ID switch and pull-high/pull-low resisters for DI on board. Users can set Card ID on a board and recognize the board by the ID via software when using two or more PCI-826LU cards in one computer. The pull-high/pull-low resisters allow specifying the DI status; when the DI channels are unconnected, the DI status will remain in high or low status other than floating.
The PCI-826LU provides two programmable trigger methods: software trigger and pacer trigger. The A/D channel scan function of PCI-826LU is so amazing, we call it MagicScan. The MagicScan controller takes out most works of getting A/D value such as select channel, set gain, settling time, trigger ADC and get data. With the built-in MagicScan and interrupt features, it is effectively off-loading your CPU from the job. Even in channel scan mode, it can have different gain code for each channel, and the sampling rate can still reach 250 kS/s totally. The PCI-826LU is suitable for high end applications.
