Pulse / Status Output
Modular I/O Current Output, active or passive, with HART
Pulse / Status Output, active or passive, highC or
Namur
Modular carrier with 1 or 2 I/O modules Each module: 1 out of following 3 in-/output
functions:
Current Output, active or passive
Pulse / Status Output, active or passive, highC or
Namur
Control Input, active or passive, highC or Namur
Profibus DP I/O Profibus-DP, active

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
