产品介绍： 48口PCI Express总线DIO卡
产品特点：
- Supports PCI Express x 1 for PEX-D48
- 48 channels of digital I/O
- Bi-direction programmable I/O ports under software control
- All I/O lines buffered on the board
- Six 8-bit bi-direction I/O ports
- SMD, short card
- Connects directly to DB-24PR, DB-24PD, DB-24RD, DB-24PRD, DB-16P8R,
DB-24POR, DB-24SSR, DB-24C or any OPTO-22 Compatible daughter boards. - One 32-bit programmable internal timer
- One DB37 connector, one 50-pin box header
- One 16-bit event counter
- Interrupt source: 4-channel
- Card ID function for PEX-D48
- Pull-up or pull-down resistors on I/O lines
- Emulate two industrial-standard 8255 PPI ports (mode 0)
- Buffer output for higher driving capability
- DIO response time is about 0.77 μs (1.3 MHz max.)
