Tech Square’s PCI-7296/7248/7224 is a high-density parallel digital I/O board with 96/48/24 I/O channels. The header connectors are fully compatible with the industry Opto-22 standard. Thus, PCI-7296/48/24 can utilize the Opto-22 external devices. The PCI-7296/7248/7224 devices emulate mode 0 of the industry-standard 8255 programmable peripheral interfaces (PPI) chips. The PCI-7296/7248/7224 provides 4/2/1 PPI chips respectively. Each PPI offers three 8-bit ports: Port A, Port B, and Port C. Port C is divided into 2 nibble-wide (4-bit) ports. The PCI-7296/7248/7224 devices have programmable timers/counters. One 16-bit counter is available for event counting, while the other 32-bit timer is available for timed interrupt generation. The PCI-7296/7248/7224 devices provide multiple programmable interrupt sources from DIO channels, as well as the output of the timer.
