Compensation of thermocouples with a compensating box
As well as the error limits of the 2AI TC High Feature electronic module (see Table
"Technical specifications 2AI TC High Feature (6ES7134-4NB01-0AB0)" in this chapter) you
must also take the accuracy of the compensating box into account.
Internal compensation with TM-E 15S24-AT or TM-E15C24-AT
Factors affecting the accuracy of the temperature measurement
The connected channel with internal compensation must be
assigned parameters separately.
Rules on using internal
temperature compensation
Don't insert the 2AI TC High Feature directly next to a power
module with high incoming current (> 3 A). An incoming current of
10 A can result in a further ± 2 K error.
The station must be in a static state
1
to ensure that the specified
accuracy is achieved.
Accuracy is achieved 30 minutes after the static state has been
achieved.
Additional technical specifications
for the error limits of the
2AI TC High Feature
The overall malfunction of the channel is caused by the
combination of the input error and the internal compensation
error.

The static state is defined by an almost constant ambient temperature (no draft, for example, in a
closed cabinet!)
