I am replacing an old TI PLC and T/C input modules with Automation Direct's DL405 and Terminator I/O modules. The existing system utilizes 'ISOTHERMAL BLOCKS' between the T/C junction and the Input to the card. Is this required with my new PLC as well? Or does the Cold Junction compensation feature serve the same purpose?

there is a big differnece between "should" and "does".
it pays to do a loop check on your calibration in the shop. CJ compensation is not yet an industry standard practice and you can find yourself up to you neck in alligators pretty quick.
