2.2 Current output I
• The current output is galvanically isolated from all input and output circuits.
• Setting data and functions can note down on page 0/3.
Please also refer to Sect. 3.2 “Factory settings”.
• Typical current output
• All operating data and functions can be set.
• Display version: IFC 090 D, see Sect. 4 and 5.6, Fct. 1.05 for operator control
Basic version: IFC 090 B, see Sect. 6.2 for operator control
• The current output can also be used as an internal voltage source for the binary
outputs and inputs.
