Isolated
Output
Option
and 4-20 mA
Adjustment An isolated 4 to 20 milliampere (mA) output is an available option. The isolated output is available by
connecting a loop powered isolator module to the transmitter output. The modules have their own set of
output terminals which provide an isolated 4 to 20 mA output equal to the non-isolated instrument output.
This one-to-one current isolation is used to prevent instrumentation ground loops. See
Figure 14 for the wiring diagram to install the isolated output module.
Use of the isolator module will add a small signal conversion error to the instrument output and limit the
output load to 350 ohms.
Factory Setup of IF302
FCI sets the tags on the AI blocks that contain the signal connection to the Flow channel and the Temperature
channel identifying them as shown below.
Other configuration and tag definitions are left to the system integrator.
