Analog Output Mode (HART Communication Disabled)
If you have an unused HART channel, you can use it as a 4-20mA current sinking analog
output.
In FBxConnect, you must Disable the 250 Ohm Termination Resistor and set the HART
Comm Mode to Disabled.
Figure 3-14
shows two examples for wiring a HART channel as a 4-20mA analog output.
In the figure, an externally powered current loop receiver connects to Channel 1 and a
24VDC loop supply-powered current loop receiver connects to Channel 4.
