A/D-D/A 12Bit  PCI  
The PCI bus 12 bit data acquisition card is a high precision data conversion/acquisition system. It contains 16 analog to digital channels with unipolar or bipolar input, 2 digital to analog channels with unipolar or bipolar output and 1 digital I/O channel with 16 bit line. The on board 8254(71054) chip provides programmable interval timer/counter functions to trig A/D conversion. The PCI bus 12 bit data acquisition card also provides interrupt driven for convention A/D input.
