The PCIe-DIO24 is a 24-channel digital I/O board with selectable 3.3V or 5V logic levels for PCI Express bus compatible computers. The 24 bits function as an 8-bit Port A, an 8-bit Port B, and an 8-bit Port C, which may be further divided into two 4-bit ports (Port C-HI and Port C-LO).
There is a 10 kOhm pull-up/pull-down resistor network associated with each digital port. Their direction is software selectable and stored on the board, so the user can use the board in a different PC without running configuration software: simply set the board number in InstaCal.
The PCIe-DIO24 is connector and software compatible with Measurement Computing's highly popular PCI-based PCI-DIO24 and ISA-based CIO-DIO24 boards, making migration from the ISA or PCI bus about as simple as unplugging the digital I/O cableÕs 37-pin connector from the old board and plugging it into the new one. The PCIe-DIO24 is also supported by the same wide variety of external relay and solid state I/O module racks.
The PCIe-DIO24 is completely plug-and-play. There are no switches, or jumpers on the board. All board addresses, interrupt channels, etc. are set by your computer's plug-and-play software.
"When we started designing these systems, we needed to locate a robust data acquisition unit that we could trust, have multiple inputs and a simple but effective software interface and a reasonable price." Michael Gray, Precia Molen
"We have used MCC devices for many years on any number of different projects, from pile testing to seismic tests, and we've always been more than satisified with their performance. This was the natural choice for us." Stephen Kemp, Manager, GBG Structural Services
