3.4.5. Input Sensor Wiring
Connect the input sensors as shown in Figures below for RTD, thermocouple, mV and ohm
connections.
Figure 12 – HART/DE Input Wiring Diagram for single sensor connection
The single sensor connections can also be used on a dual input transmitter when a second input is not
required. In this case, it is recommended that the second input be configured to None in the software.
In case of RTD type being configured for 4-wire, the configuration for single input is automatically
done.
