6.1.7 Connection of the "Analog I/O" module for active usage
• In the active usage the supply voltage for the communication line is supplied by the
device itself. There is no need of an external power supply.
• The wiring must be in accordance with the intended operating mode of the Analog I/O
module; see the drawings below.
• Maximum current consumption of the connected HART devices: 24 mA
(i.e. 4 mA per device if 6 devices are connected).
• Output voltage of the Ex-d module: 17.0 V@4 mA to 10.5 V@22 mA
• Output voltage of the Ex-ia module: 18.5 V@4 mA to 12.5 V@22 mA
"Operating mode" = "4..20mA output" or "HART slave +4..20mA output"
