INT7

24 Bit A/D Integration Board for PCI

INT7 board is direct successor of the classical ISA board INT5,

with which it has in common the implementation of analogue

channels and accordingly consonant key electrical parameters.

Among the major advantages counts:

•

designed for PCI slot of current PCs

•

Plug and Play technology simplifies the installation process

under contemporary Windows OS versions

•

four channel version directly on one board - the card uses up

the space of one PCI slot only

•

using the Surface Mounted Technology (SMT) the board gains

on reliability and compactness

•

improved thermal stability

Unlike the INT5 board, each channel is equipped with one input

(the subchannels were abandoned) and also dierent wiring of

the connector has been used.

Reduction connector for replacement of INT5 boards can be

supplied on demand.
