Thermocouples
5.3 Compensation for the reference junction temperature
Analog value processing
92 Function Manual, 06/2014, A5E03461439-AC
Temperature condition with "Fixed reference temperature" setting
The figure below shows the connection options for thermocouples provided the temperature
of the module is kept at a fixed reference temperature (20 °C), for example by installing it in
an air-conditioned switch cabinet. The reference junction is in the module.
Thermocouple without compensating line
Thermocouple via compensating line
Compensating line (same material as thermocouple)
