USB 6211

Hi,
Can I use USB -6211 to be like a relay to turn ON and OFF the signal?  The signal ON/OFF should happen instantly like a relay, no ramping.

Hi mnk,

The USB-6211 will not quite work like a relay as there is no way of physical disconnecting its pins. However, if you simply wish to output signals ON (5V) and OFF (0V), you can do so by simply writing the appropriate value on the pins. Since this is an analog output, there will be some ramping at a very fine level. The specifications claim that we have a 5V/us slew rate, but this can vary depending on what load you connect this to. Examples on how to write to your analog output channels can be found in our LabView shipping examples.

I hope this helps,S_Hong
