ISO-AD32 Series

  200KS/s 12 bits 32 channel isolated analog input board

Functional Description
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 500Vrms of common-mode voltage.
The ISO-AD32H/L features a 200KHz 12-bit analog-to-digital converter ,on board 1 K byte 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 200KHz sampling rates for  single channel or 100KHz sampling rates for channel scan .
The "Hands-Off" design permits all board parameters (channel selection, gain, input type ,operating mode ) to be performed in software . Once installed , you will never have to take care it again.
The board's innovative design improve several drawbacks of the conventional isolated A/D card . Such as :
1.The speed is faster ; up to 200KHz
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 .
Features:
  •  32 single-ended or 16 differential input channels, 500VDC photo-isolation protection
  •  Maximum 200K 12-bit sampling rate
  •  Built-in 1K byte FIFO
  •  Single -ended or differential input, can be jumper selectable
