Connecting To 4-20 Ma Output Terminals - Abb Sensi+ Gla533-Ng Installation And Commissioning Manual

Connecting to 4–20 mA Output Terminals
The 4–20 mA analog output (AO) terminals come with a default factory configuration.
The 4 mA value corresponds to the minimum displayed value in the Measurements panel and the 20 mA
value, to the maximum displayed value (see "Measurements Panel" on page 45). The analog output is
linear in between these two thresholds.
WARNING
Use only recommended shielded cables for wiring the 4–20 mA outputs interface.
By default, these AO terminals are in passive mode. They can be put in active mode if need be (for
more information, refer to the Sensi+ User Guide).
