Measurement of CJC for 1 of 3 SCC-TC modules

[Slapman]

There are multiple SCC modules (> 9) being monitored of various signal types. Is it possible to read the cjc on a t/c/ module along with the other signals in the SC-2345 box

Measuring CJC from TC module on SCC-2345

Hey Slapman,
The SCC-2345 routes the signals like this:
Thermocouple = channel X
CJC = channel X+8

TC module in J1:: Temp reading from channel 0 of DAQ card and CJC from channel 8 of DAQ card.

Also, if you create a DAQmxTask, you can select "built in" for the CJC value and it will automatically be taken into account by the task.

Hope that helped.

Thanks for the reply Brett"

I agree and understand your response for the t/c measurement

One aspect that I was looking at was the ability to monitor the following configuration effectively:
SCC t/c module in J1 and use J8 for CJC
SCC 1V analog module in J2
SCC 5V analog module in J9

Would this work by acquiring a config of ch 0 for t/c, ch 8 for cjc, ch 1 for V, and ch 9 for V?
Or does it have to go ch's 0,1,8,9

Thanks,
