INT7
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.
Full size PCI 2.0, 32 bit PCI slot is required. Low profile or
PCI Express slots cannot be used.
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.
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.
