INT5 - A/D Converter (internal ISA)

INT5 Converter

INT5 is an internal 24-bit A/D converter board for measurement of voltages of chromatographic and electrochemical detectors.
The board is designed for the ISA bus and is equipped with mechanical jumpers for manual setting the base address and interrupt. It contains one to four fully independent, galvanically separated sigma delta integrating A/D converters for processing positive and negative voltages.

  • INT5 internal ISA board has been discontinued from sale since 2003.

Upgrade options

Most current PC computers do not have the obsolete ISA slot for this card. When upgrading the PC it is recommended to upgrade to INT7 internal PCI board. The INT7 board is a direct successor of the INT5 control board.
