Optional Equipment
National Instruments offers a variety of products to use with your
PC-DIO-24/PnP board, including cables, connector blocks, and other
accessories, as follows:
• Cables and cable assemblies, shielded and ribbon
• Connector blocks, shielded and unshielded 50-pin screw terminals
• SCXI modules and accessories for isolating, amplifying, exciting,
and multiplexing signals for relays and analog output. With SCXI
you can condition and acquire up to 3,072 channels.
• Low channel-count signal conditioning modules, boards, and
accessories, including conditioning for strain gauges and RTDs,
simultaneous sample and hold, and relays.
For more specific information about these products, refer to your
National Instruments catalogue or call the office nearest you.
Note: The PC-DIO-24/PnP can drive the SSR-ODC-5 output module and all SSR
input modules available from National Instruments, but cannot reliably
sink sufficient current to drive the SSR-OAC-5 and SSR-OAC-5A output
modules.
To drive a SSR-OAC-5 or SSR-OAC-5A, you can either use a non-inverting
digital buffer chip between the PC-DIO-24/PnP and the SSR backplane, or
use another National Instruments board with higher drive current.
Custom Cables
National Instruments offers cables and accessories for you to prototype
your application or to use if you frequently change board
interconnections.
If you want to develop your own cable, however, the following
guidelines may be useful.
The PC-DIO-24/PnP I/O connector is a 50-pin male ribbon-cable
header. The manufacturer part numbers used by National Instruments
for this header are as follows:
• Electronic Products Division/3M (part number 2550-5002)
• T&B/Ansley Corporation (part number 609-5007)
