I have a myRIO (board only) and I need to read type K thermocouple measurements for an internal PID. Am I able to do this directly into the board? Or will I need an adapter?
Please be as specific as possible.
Thank you.

You will need a way to connect to the MXP connectors on the myRIO.
The following MXP Breadboard is an example.

Thanks for the reply!
Is there a wiring diagram for doing this? I am not an electrical engineer, so please bear with me.

The MXP connectors just plug in to each other. You just need the female version of the connector.

So am I able to plug this directly to the myRIO board? I have the board only.
And is there a wiring diagram for the thermocouples? I assume each row in the MXP is represented by a pin that connects to the board, so is there a particular order I need to attach the thermocouples? Or can I just specify in the LabView which row corresponds to the + or - of each thermocouple?
Thank you for your help and patience!

The above listed connector is the connector for the myRIO board only.
Aditionally, the k type thermocouple has a + and - connection. So the + needs to go to one of the analog inputs and the - needs to go to AGND, analog ground. See page 5 of the below myRIO 1950 manual for the connector pinout.

Thank you!
This is exactly what I'm looking for!
