6.1.7 Connection of the "Analog I/O" module for passive usage
• In the passive usage the supply voltage for the communication line must be supplied
by an external source.
• The wiring must be in accordance with the intended operating mode of the Analog
I/O module; see the drawings below.
• Screened cable must be used for the 4...20mA signal line.
"Operating mode" = "4..20mA output" or "HART slave +4..20mA output"
