Compensation of thermocouples with a compensating box
As well as the error limits of the 2AI TC ST electronic module (see Table "Technical data
2AI TC ST (6ES7134-4JB00-0AB0)" in this chapter) you must also take the accuracy of the
compensating box into account.
Compensation of thermocouples with a Pt100 on the 2AI RTD ST
Factors affecting the accuracy of the temperature measurement
Ensure there is good thermal contact between the reference
junction and the Pt100 used for compensation.
Wiring rules
We recommend that you wire the Pt100 with a four-wire
connection.
The accuracy of the thermal resistor (Pt100) used for
compensation must be taken into account.
1
Additional technical data on the
error limits of the 2AI TC
The error of the measurement input (2AI RTD ST) used for
compensation must be taken into account.

In the case of thermocouples with a characteristic curve with a very shallow gradient, these errors
can lead to a major measurement discrepancy.
For the following thermocouples, this causes a limitation of the input range of the thermocouples in
which the accuracy information in the manual applies:
• Type N: -100 °C
• Type K: -230 C
• Type E: -230 C
