PCL-730 User Manual 2
1.1 Introduction
The PCL-730 offers 32 isolated digital I/O channels (16 DI and 16 DO) and 32 TTL
digital I/O channels (16 DI and 16 DO) on a PC add-on card. Providing 2500 V
DC
iso-
lation, each I/O channel corresponds to a bit in a PC I/O port, making the PCL-730
very easy to program. The PCL-730 offers one PC interrupt with jumper-selectable
IRQ.
