INT9 - internal 24-bit A/D converter for PCI

INT9 Comming soon:
The new A/D converter is now in the stage of BETA testing. Contact us by email sales@dataapex.com for further details.

INT9 is an internal 24-bit A/D converter card that measures the voltages of chromatographic and electrochemical detectors. It contains up to four data-acquisition channels on one board (one and two channel versions are also available). The channels are completely independent, equipped with A/D converters using continuous integration and able to process both positive and negative voltages. INT9 can simultaneously perform data acquisition from multiple detectors. Individual channels can be assigned to different chromatographs. The card includes four digital inputs and eight digital outputs. The first four digital outputs are also equipped with relay contacts. Digital inputs and outputs are generally used to synchronize Start and Stop of the analysis with autosampler or chromatograph. However, Clarity Event table enables to use them to trigger various actions or to control additional devices. The card provides excellent reliability and temperature stability.

Full size PCI 2.0, 32 bit PCI slot is required. Low profile or PCI Express slots cannot be used.

INT9 is a modernized successor of the successful INT7 PCI card.

Advantages of the INT9 A/D converter:

Continuous integration of input signal.
The amount of data entering the computer is substantially smaller, since individual data items already represent partial integrals.
Isolations prevent noise from both other channels and from the PC.
Integration frequency up to 400 Hz enables Fast GC application.
