Digital I/O Boards

[Avital]

Hello,

I need a digital I/O card. Thetichnical requests are as follows:

a. Maximal sampling time is 30msec.

b. Input and output voltage range is 0-35V (35V is the maximum).

c. An option to choose for every input and output the "input low", "input high", "output low" and "output high" voltage ranges.

d. There are at least 25 inputs and 25 outputs in the board.

e. I would rather a PCI card, if it's possible according to the requirements above.

I visited your site, but failed to find the  appropriate card.

Asking your help to find the exact card.

Thanks,

Avital.

Hi Avital,

I was unable to locate a card that has exactly those specifications, but there are a few solutions for you to consider.  The PCI-6528 can achieve most the specifications, but it is two channels short of your 30 channel requirement and you will not be able to select the logic levels natively. 

For selecting logic levels at that high of a voltage, I would recommend looking into a Schmitt Trigger to add externally to your PCI card.  You can find more information about this circuit here.  It acts as a logic level selector for your card by outputting on and off voltages based on your input/output signal.

For channel count, if you wanted to look into getting two PCI digital I/O cards to place in your system, that may be a viable option for you.  If that is undesirable, I would point you to a PXI system or a SCXI system.
