ACCES I/O Products Inc. (San Diego, CA) released a line of low-cost PCI isolated digital I/O cards offering a range of 16, 32, or 48 individually optically isolated inputs or outputs (channel to chan- nel, channel to ground). Individual channel-to-channel isolation allows for every channel to be physically and electrically separated from the others. The opto-isolated outputs use solid-state, P-Channel FET switches, providing fast turn-on and turn-off time. Inputs feature a change-of-state detection capability that provides a means to automatically interrupt the host computer in real time. When one or more input bits change state, a PCI inter- rupt is generated to automatically wake up an application. Each input is rectified by photo-coupler diodes and is therefore polarity insensitive — either positive, negative, or AC voltage inputs are acceptable. The input range is up to 60 VDC or AC rms at frequencies of 40 to 10 kHz. User-supplied load voltages can range from 5 V to 60 V. The device is suited for high common-mode external voltage environments. Other features include universal PCI, PCI-X, 3.3 V, and 5 V compatibility.For Free Info Visit http://info.hotims.com/10964-412 Embedded Systems Conference Booth #2581 |
