NI 9472 minimum external voltage supply

[HudTuner]

In the datasheet of NI 9472 it says that external voltage supply is between 6–30 VDC. But I want to use the module on TTL level (0-5VDC). Is that possible with this module?

I think it could be possible to interface that sourcing output wit TTL, but it might require some external resistors to be connected. If you have a look at Troubleshooting Digital Output and Pulse Generation on the NI 9472, 9474, 9476 & 9475, then it shows how to make the connection. In case 6V is your concern, then you could add another resistor to create voltage divider. There is even some calculator: voltage divider.

However, let me say I haven't tested this connection But theory should work.
