Extension to a Reference Junction
From their connection sides, the thermocouples can be extended by compensation
cables as far as the reference junction (transition to copper wiring) or to the
compensation box. The reference junction can also be an ET 200iS terminal
module.
The compensation cables are made of the same material as the wires of the
thermocouple. The connecting cables are copper. When connecting up, make sure
that you do not reverse the polarity.
Compensation by Resistance Thermometer on the 2AI RTD
If thermocouples connected to the inputs of the 2AI TC have the same reference
junction, compensate using a 2AI RTD.
For both channels of the 2AI TC module, you can select "RTD" or "none" as the
reference junction. If you select "RTD", the same reference junction (RTD channel)
is always used for both channels.
