ADLINK ACL-7120A/6 is a 32-CH TTL compatible Digital Input/Output and
timers/counters card for PC/AT and compatibles. The device has 32 TTL compatible
digital inputs, 32 digital outputs, and 5 channels with a 16-bit timer/counter.
The blank breadboard area is provided for user??s circuit designs. ACL-7120A/6
device supports one 32-bit timer pacer which can generate interrupt
periodically, as well as an event counter for external event counting. ADLINK
ACL-7120A/6 delivers cost-effective features and is ideal for a broad variety of
applications.
