Acces 104-DIO-48S Change-Of-State Detecting Digital I/O Card Overview
Features:
- (48) or (24) Parallel Lines of 82C55 Digital I/O with Tristate Buffers Prevent Unintended Control of External Equipment
- IRQ on Input Change of State (COS) Eliminates the Need for Constant Polling
- High Sink/Source Current 64 mA / 32 mA
- I/O Pulled up to 5 V for Contact Monitoring
- Compatible with Opto-22 and Other Industry Standard I/O Racks
The Acces 104-DIO-24S / 104-DIO-48S Change-Of-State Detecting Digital I/O Cards provide a total of 48 or 24 lines of digital I/O with counter/timer for PC/104-based data acquisition. This low-cost, high-performance, reliable board features Change of State (COS) detection on user-selected ports, allowing the board to generate an interrupt port by port. Since one READ determines the data, there is no need for constant polling, which greatly reduces processor overhead and allows applications to run more smoothly.
The 104-DIO-48S board uses two 82C55A chips to provide a computer interface to the 48 I/O lines. Each chip provides two 8-bit ports and two 4-bit ports with software programmable direction. Each I/O line is buffered and capable of sourcing 32mA or sinking 64mA. Pull-ups to 5V are provided for contact monitoring. Optionally available is an 82C54 chip that includes three 16-bit counter/timers factory configured in an optimal module for use as event counters, frequency output, pulse width, and frequency measurement. Connections are made via two industry-standard 50-pin headers plus one ten-pin header for the optional counter/timer.

AMAZING PEOPLE. AMAZING WORK.
- Karen C. Google
I find the employees helpful and knowledgeable about their products.
- Young L.
Artisan isn’t just a supplier with inventory. Their engineers helped diagnose a problem over the phone that would have taken us weeks to figure out!
- Angie R. Facebook
Fantastic company with great people! We are lucky to have them in Champaign!
- Mike A.
I got the package. SBC worked out great. We are back in business. Much appreciated! Artisan has saved the day again....
- Neo Google
Contacted Artisan for hard to find that has been out of circulation for nearly a decade. Their rapid response and availability exceeded all other suppliers. They supplied the part overnight to an out of state facility which allowed us to repair our equipment successfully. Well packed electronics. Well stated and professional documentation. I work with a hundred different suppliers any day of the week in my profession. Artisan remains at the very top of the bookmark tab. Thanks so much.
- Gareth A.
We bought a Parker Compumotor Controller for our press and installed it 2 weeks ago. Easy fix for our machine and it is working perfect.
- Debbie A. Google
Great company with great people. Always a pleasure to do business with Artisan!
