The 12 bit data acquisition card is a high precision data conversion/acquisition system for PC/XT, PC/AT, PC/386, Pentium or compatibles. It contains 16 analog to digital channels with unipolar or bipolar input and 4 digital I/O channels with 8 bit line for each channel. The on board 8254 chip provides programmable interval timer/counter functions to trig A/D conversion. The 12 bit data acquisition card also provides interrupt driven for convention A/D input.


The features of the 12 bit data acquisition adapter are:


  • Provides 16 A/D channels and the resolution is 12 bits.]
  • Unipolar or bipolar selectable.
  • Input voltage range from 0 to 10V or 0 to 20V for unipolar, and from –5V to 5V or –10V to 10V for bipolar.
  • Provides 4 digital input/digital output channels and the resolution is 8 bits.
  • Provides three independent 16 bits counter to trig A/D conversion.
  • I/O port address selectable.
  • ISA bus interrupt programmable (IRQ3 to IRQ15).
  • Gain control factor selectable from 1 to 8.
