features and benefits
The PEX-D24 series utilizes the PCI Express bus and is designed as an easy replacement for the PIO-D24/PIO-D24U series without requiring any modification to either the software or the driver. The PEX-D24 provides 24 buffered TTL Digital Input/Output lines. The PEX-D24 also includes an onboard Card ID that enables the board to be easily recognized via software if two or more cards are installed in the same computer.
- PCI Express x1 Interface
- Supports Card ID (SMD Switch)
- Emulates two Industrial-standard 8255 PPI Ports (Mode 0)
- DI/O Response Time approximately 2 μs (500 kHz Max.)
- 24 Buffered TTL Digital Input/Output Lines
- Three 8-bit Bi-directional I/O Ports
- DO Provides Higher Driving Capability
- Four Interrupt Sources
