Low-Cost Digtial I/O Card compatible with Labview (ISA or PCI, 3.3v or 5v)

[Anonymous]

Hi,

I only need 16 i/os or less, but its seems all the cards I've found
either dont mention they are directly supported
within Labview, or they have too many I/Os and are too pricey (i.e.
National Instruments brand)!)

Anyone know where I can get a cheap I/O card, preferably with
selectable 3.3V or 5V operation.

Thanks!

What do you consider cheap?

How about $89 for the PCI-DIO24 from Measurement Computing including LV drivers...

Hi,

  I think that the cheapest way is to develop a specail hardware to extend I/O port using PC usb or parallel port.

Good luck,

Hello Anonymous,

If your are looking at DI/O device with 16 channels for TTL signals, consider the following for your application:

USB-6501 24-ch 8.5mA

PCI-6503

These instruments as fully compatible with LabVIEW. If you need more information on these devices or other hardware solutions feel free to contact us. We will be glad to assist you.

If I'm not mistaken, the PCI-DIO24 is not compatible with winXP.   Which, if thats the case, I'm guessing that Labview doesnt support it either.

Can someone verify this?

Hi All-

Sandra's suggestion of the USB-6501 is probably your best bet.  It is fully supported by NI-DAQmx (the device driver, included with the purchase of the device) and LabVIEW (currently versions 8.2.x, 8.0.x, and 7.1.x) under Windows 2000/XP/Vista.  It's inexpensive and supports 3.3V/5V selectable operation.  It is the lowest cost option from NI (other than the USB-6009, which does not meet your I/O count needs) that supports configurable digital logic levels.
