NI 9401 vs 9403 inputs

[ry78]

Hi, according to the NI 9403 datasheet all inputs have Schmitt triggers and pull down resistors. Does the NI 9401 have this same feature? I could not locate this in the datasheet. Can someone enlighten me?

Thanks

Hi Ryan,

The NI-9401 does not have this feature; the NI-9403 is the only C Series module that uses Schmitt triggers. You should also note that the 9403 only has access to counters when used with our cRIO products.

Best of luck with your application.

Ok, thanks Lindsey for the response and additional information.
