Description
The DAQCard-DIO-24, carrying the part number 182680F-01 (776912-01), falls under the category of Legacy DAQ Devices. This device is built around the 82C55A PPI chip and is designed to be compatible with Type II PCMCIA slots. It is equipped with 24 programmable I/O pins, distributed across three 8-bit ports. These ports support a variety of operation modes, including Strobed I/O, Bidirectional Bus I/O, and Simple I/O.
The DAQCard-DIO-24 features a comprehensive I/O Channel Interface that includes a data bus, address bus, support and control signals, interrupt lines, card information structure, timing interface circuitry, data buffers, PC Card control registers, and an address decoder. For connecting to external devices, it utilizes a 25-pin I/O connector. An optional cable, the PSH27-50F-D1, is available for those looking to connect this card to a 50-pin standard male connector and compatible NI accessories like the SC-2051 and CB-50.
For powering any external digital circuitry, the DAQCard-DIO-24 offers a +5 V supply through Pin 25. Its current draw is approximately 60 mA, ensuring efficient operation. It’s important to note that this device has been announced as obsolete by National Instruments, indicating that it may no longer be available for purchase or supported in the future.
