A-822PGL / A-822PGH and A-821 series

  AT-Bus 12 bits  multifunction card

Functional Description
The A-822PGH/L are 12 bit multifunction analog and digital I/O boards for the PC/AT compatible computer. The A-822PGH/L offer 16 single-ended or 8 differential analog inputs, plus two channels of analog output with 12-bits resolution. In addition, The A-822PGH/PGL has 16 digital input, 16 digital output , one timer/counter channel. The A-822PGH Provides gain of 0.5, 1, 5, 10, 50 ,100 , 500 , 1000 while the A-822PGL provides gains of 0.5 , 1 , 2 , 4, 8 . It has a maximum sampling rate of 125 K samples /s, DMA operation is jumper selectable for levels 1 or 3. Interrupts are jumper selectable between 3 and 15.  A-821 differences: only single ended inputs, max 45kHz troughput, 1 channel DA, limited programmable gain.
