Introducing the PCI-DAS08

Overview: PCI-DAS08 features

This manual explains how to configure, install, and use your PCI-DAS08 board. The PCI-DAS08 is a
multifunction measurement and control board designed to operate in computers with PCI bus accessory
slots.
The PCI-DAS08 board provides the following features:
Eight single-ended 12-bit analog inputs
12-bit A/D resolution
Sample rates of up to 40 kHz
±5V input range
Three 16-bit counters
Seven digital I/O bits (three input, four output)
Connector compatible with Measurement Computing's ISA-based CIO-DAS08 board
The PCI-DAS08 board is completely plug-and-play compliant, with no switches or jumpers to set.
Configuration is controlled by your system's plug-and-play software. A functional block diagram of the
PCI-DAS08 is shown here.
