PCIe-DIO24, PCI-DIO24 24-Channel Digital-I/O PC-Boards
The PCIe-DIO24 and PCI-DIO24 are 24-channel digital-I/O PC boards for PCI-Express or StandardPCI bus. The 24 channels are organized in 2x 8 bit and 2x 4 bit ports according to the 82C55 structure.
- 24 digital-I/O channels: 2x 8 bit ports, 2x 4 bit port - each port can be programmed as input or output.
- Easy to use and easy programming.
- Interrupt capable.
- Model for PCI-Express and Standard-PCI.
- PCIe-DIO24: High current output, and 82C55 mode 0 emulation.
- 37-pin D-sub male connector.
