Figure 3
shows how to wire a HART channel for devices which do not use loop power but get power
from an external power supply.

Analog Input Mode (HART Communication Disabled)
If you have an unused HART channel, you can use it as a 4-20mA analog input (AI current mode).
In FBxConnect, you must Enable the 250 Ohm Termination Resistor and set the HART Comm Mode
to Disabled.
Figure 4
shows two examples for wiring a HART channel as a 4-20mA analog input. In the figure, an
externally powered current loop transmitter connects to Channel 1 and a loop powerd current loop
transmitter connects to Channel 4.
