The A-821PGH/L is 12-bit multifunction analog and digital I/O boards for the PC/AT compatible computer. The A-821PGH/L offer 16 single-ended or 8 differential analog inputs, plus two channels of analog output with 12-bit resolution. In addition, The A-821PGH/PGL has 16 digital input, 16 digital output, and one timer/counter channel. The A-821PGH Provides gain of 1, 10,100 , 1000 while the A-821PGL provides gains of 1 , 2 , 4, 8 . It has a maximum sampling rate of 45 k Samples/Sec. . Interrupts are programmable 3 and 9 and provide one channel D/A output.
ICP DAS discontinue the /NDA model (without D/A function) since the standard model provides full functions that covers the requirement for /NDA version. Please contacts us for OEM/ODM project if you are interested on customized version (or /NDA model).
