how can I make a high voltage temperature measurement with compactRio%3F

I need to measure the temperature of a wire that is above 50Vdc. I would prefer not to have to figure out how to electrically isolate the sensor from the wire while maintaining the temperature measurement integrity. I understand that I can use an isolated analog input module. But, I thought I'd ask the community what cRIO module would be best. 

 

Basic details:

- measure temperatures as high as 300 degrees C

- sensor is in contact with metal raised to ~50Vdc

 

Any suggestions?

Sorry all. I didn't realize that multiple cRIO thermocouple modules already have built-in isolation.  <sheepish grin>
