3.4.4 Temperature measurements
Temperatures can be measured in the field multiplexer system using MCR temperature
measuring transducers from Phoenix Contact. They are connected in front of analog input
terminals (see Figure 3-5).
Figure 3-5 Circuit diagram “Temperature measurement”
Make sure that the same transmission mode (copper) is always set for both field
multiplexers.
You will find MCR temperature measuring transducers that can be used in the field
multiplexer system in Section “Ordering data” on page 65. PT 100 and thermocouple
sensors can be connected to these types.
