Product Specs

The PCI-DIO96H and PCI-DIO48H are high density, logic level, digital I/O boards for IBM or compatible PC’s with a PCI bus. The PCI-DIO96H offers 96 bits of digital I/O, while the PCI-DIO48H has 48. For both boards, the I/O, in 24-bit groups, is based on an 82C55, mode 0 emulation. Each group provides an 8-bit port A and port B, as well as an 8-bit port C that can be split into a 4- bit port C-HI and a 4-bit port C-LO. The digital output drivers are 74S244 chips, and provide 64 mA sink and 15 mA source output capabilities. The input buffers are 74LS373 and offer the high standard input impedance of the 74LS series. On power up and reset, all I/O bits are set to input mode. Like all members of the 74LS series, unconnected inputs will typically float high. If you are using the board to control items that must be OFF on reset, you will need to install pull-down resistors. Provisions have been made on the board to allow users to install SIP resistor networks quickly and easily in either pull-up or pull-down configurations.
