How to connect a linear encoder with ni 6008?

I would like to connect a linear encoder using ni 6008 but i don't know how to do it.

I know that ni 6008 has one PFI channel. 

Can i use other digital channel in combination with the PFI to connect the encoder?

 

Thank you

Francisco

Hi Francisco,

 

connecting is one problem - the other (and more important) one is analyzing the signals…

 

The USB6008 has only one high-speed PFI, all those other DIs are only software-timed and so just capable of ~100Hz sample rate. When your encoder is rather slow (or only outputs a low amount of pulses in relation to movement) you could use the AI pins to read the signal (capable of 10kS/s in sum) - with the disadvantage of doing the signal analysis on your own…

Best regards,

Thank you for your quick replay!!!!

What about using a Ni USB 6210?

Hi Francisco,

 

as the manual explains you could use that device to measure with quadrature encoders…

Best regards,
