Description
The DAQCard-DIO-24 is an essential component within the Legacy DAQ Devices category, having the part number 776912-01. This device is built on the 82C55A PPI base technology, ensuring reliable performance and compatibility. It is specially designed to fit seamlessly into Macintosh and PCs that come equipped with a Type II PCMCIA slot, making it a versatile choice for a wide range of applications.
Featuring 24 programmable I/O pins, which are distributed across three 8-bit ports, the DAQCard-DIO-24 offers flexibility in handling various data inputs and outputs. Users can leverage different operation modes, including Strobed I/O, Bidirectional Bus I/O, and Simple I/O, to suit specific project needs. This adaptability is further enhanced by its comprehensive I/O Channel Interface, which includes a card information structure, timing interface circuitry, data buffers, PC Card control registers, and an address decoder.
The device comes equipped with a 25-pin I/O connector, ensuring easy and secure connections. For those requiring extended connectivity options, there is an optional cable, the PSH27-50F-D1, which facilitates connection to a 50-pin standard male connector and other NI accessories. This feature underscores the DAQCard-DIO-24’s commitment to versatility and user convenience.
Power supply to external digital circuitry is efficiently managed through +5 V (through Pin 25), with an approximate current draw of 60 mA. This aspect of the design ensures that the DAQCard-DIO-24 can perform optimally without imposing excessive power demands on the system.
Although it has been announced as obsolete by National Instruments, the DAQCard-DIO-24 remains available for purchase and repairs through Apex Waves. This availability ensures that users can continue to benefit from its robust functionality and technical specifications.
