Introduction

The PCL-720+ digital I/O and counter card is PC-compatible add-on cards with 32 digital input channels, 32 digital output channels and three programmable counter/timer channels.

Their digital I/O channels are TTL-compatible and use 74LS244 driver/ buffer circuits to provide high output driving capacity. These buffered circuits also require lower input loading

current than regular TTL circuits. The cards' 8254 programmable counter/timer provides three ﬂexible 16-bit counter/timer channels. You can generate waves and pulses by programming

the 8254. Jumper settings determine the clock crystal frequency. The cards also includes a breadboard area perfect for customized circuits.
