4.4 Non-"Ex i" I/O connections
The following non-intrinsically safe I/O (inputs/outputs) are available:
Notes:
• The options separated by “/” are software selectable (can be changed by the user).
• The options separated by “or” are hardware versions (must be ordered as such).
• All outputs are passive unless otherwise indicated.
• HighC means High Current input/output, Namur means that the in-/outputs are according to
the NAMUR NE43 standard.
