» Functional Description
The A-823PGH/L and A-822PGH/L (H for high gain; L for low gain) are 12-bit multifunction analog and digital I/O boards for the PC/AT compatible computer.
The A-823PG/A-822PG offers 16-channel single-ended or 8-channel differential analog inputs, plus two channels of analog output with 12-bit resolution.
In addition, The A-823PG/A-822PG has 16-channel digital input, 16-channel digital output, and one channel timer/counter.
Its sampling rate can reach 125K samples/second.
The DMA operation is jumper-selectable for levels 1 or 3. Interrupts are jumper-selectable between 3 and 15.
The A-823PG provides unipolar and bipolar D/A output, while the A-822PG provides only unipolar D/A output.
