INT7 - PCI Board of A/D Integration Converters

Out of production since 2009, Product replaced by INT9, Single channel INT7 A/Ds available from a stock ( as of June 2010)

INT7 is an internal 24-bit A/D converter board that measures the voltages of chromatographic and electrochemical detectors. It contains up to 4 data-acquisition channels on one board (one and two channel versions are also available). The channels are completely independent, sigma delta integrating A/D converters, used for processing positive and negative voltages. The board includes four digital inputs and eight digital outputs. The first four digital outputs are also equipped also with relay contacts. The board is manufactured using the SMT montage and provides excellent reliability and temperature stability.

INT7 is the direct successor of our classic INT5 ISA card. The two share an identical analog channel design and thus, identical basic electric parameters.

Required PCI slot:

Full size PCI 2.0, 32 bit PCI slot for 5V 32 bits half-length extension card.
Low profile or PCI Express slots cannot be used.

Advantages of the INT7 A/D converter:

• No loss of input signal during integration. There are no time delays during which the converter fails to integrate the input signal.
• There is no continuous servicing of the input analog switches, which would otherwise cause errors (offset, noise, etc.).
• The amount of data entering the computer is substantially smaller, since individual data items already represent partial integrals.
