3.3 Monitor 4-20 mA Transducer Input
To view the reading of a 4-20 mA transducer, connect wires from a 4-20 mA transducer to
the device as shown in
. In the portal, this reading will be displayed under the
4-20
mA Input
. Use the
Config
page to select the proper sensor range and units for the
transducer being used. If the value shown for
4-20 mA Input
does not match a manual
reading, use
4-20 mA Input Offset,
on the web portal, to calibrate.
Figure 7
– Monitor 4-20 mA Input
If your 4-
20 mA transducer isn’t reading correctly wired as shown in
, it may
provide a voltage, which interferes with the board voltage. If your transducer provides a
voltage, you will need to connect the wires as shown below.
