mPCIe-DIO-24S
mPCIe 24-Channel Digital I/O with Change-of-State (COS)

- Optional Accessories
The mPCIe-DIO-24S is a 2260/2280 size mPCIe Card and optional cable assembly (D-Sub 37-pin Male connector) designed to be easily panel-mounted in any application environment. It uses the high speed PCI Express bus to transfer digital data to and from the card. The digital I/O is compatible with 8255 PPI chips making it easy to program.
The card provides three 8-bit I/O ports designated A, B and C. Port C can be further divided into two 4-bit nybbles. Each port can be programmed as inputs or outputs. Change of State (COS) detection and interrupt capabilities are designed to relieve software from polling routines that can consume valuable processing time. Each port can be programmed for detecting state changes on their lines, in which any changes of the enabled port’s bits (low-to-high or high-to-low) will generate an IRQ. An ISR (interrupt service routine) then determines which bit changed state and clears the interrupt.
The mPCIe-DIO-24S is excellent for use in applications sensing inputs such as switch closures, 5V, LVTTL, CMOS logic and controlling external relays, driving indicator lights, and more.
