The ISO-AD32H/L ( H for high gain / L for low gain ) is a bus-type isolated 12-bit A/D board for PC/AT compatible computers. The isolation inputs can operate with up to 500 Vrms of common-mode voltage. The ISO-AD32H/L features a 200 kHz 12-bit analog-to-digital converter ,on board 1 KB FIFO buffer ,32 singled-ended or 16 differential analog input channels .The analog input allows auto-channel /gain scan . This board support gap-free A/D conversion at 200 kHz sampling rates for single channel or 100 kHz sampling rates for channel scan . The “Hands-Off” design permits all board parameters (channel selection, gain, input type, and operating mode ) to be performed in software . Once installed , you will never have to take care it again. The board’s innovative design improves several drawbacks of the conventional isolated A/D card . Such as : 1.The speed is faster ; up to 200 kHz 2. The sampling rate can be programmable 3. On board FIFO buffer support gap-free A/D conversion and work well under NT and 95 environment. 4. High channel count input can be implemented in half size .
