제품설명
ACL-7120 is a digital I/O and count-er card for PC/AT and compatibles. It has a little of everything on-board,
including TTL compatible 32 digital inputs, 32 digital outputs, and 3 or 6 channels with a 16 bit counter/timer.
The breadboard area is provided for user circuit designs. All these features make the ACL-7120 a powerful
"Swiss Army Knife" of Digital I/O cards.
