24-Channel PCI Digital I/O Board with Standard and Low-Profile Backplates

CyberResearch® HDIO 24L digital I/O boards sink 24mA of current and operate comfortably at temperatures up to 158°F. The boards provide two 8-bit and two 4-bit ports, programmable by port. These PCI boards come with both standard and low-profile backplates so they fit both chassis sizes.

HDIO 24L digital I/O boards from CyberResearch, Inc. resist high temperatures and offer plenty of sink current, so they are ideal for input/output applications in industrial areas near furnaces and heat-treating facilities. HDIO 24L boards emulate Mode 0 of standard 8255 PPI chips for convenient, conventional programming. Port C Pin 0 and Port C Pin 4 can also be used to provide interrupts to your PC system.

A simple jumper allows users to select what happens to port settings and output values when the system is reset "hot," meaning that power is not turned off. Users can either retain the latest settings or return to a default setting. The PCI goldfingers are slotted for both 3.3V and 5V inputs.
