2.2 Non-EEx i connection of signal in/outputs
Following non-intrinsically safe signal in/outputs are available:
IO pcb
in/output functions,
U
n
< 32 Vdc, I
n
< 100 mA
U
m
= 253 V
Basic IO
Current Output active and passive, with HART
Status Output / Control Input
Status Output
Pulse / Status Output
Modular IO
Current Output, active or passive, with HART
Pulse / Status Output, active or passive, highC or namur
Modular carrier
with
1 or 2 IO
modules
each module: 1 out of following 3 in/output functions:
- Current Output, active or passive
- Status / Pulse Output, active or passive, highC or Namur
- Control Input, active or passive, highC or namur
Profibus DP IO Profibus-DP, active
Fieldbus IO
Profibus-PA or
Foundation Fieldbus
Notes
- the options separated with slash "/" are software selectable (can be changed by
user)
- the options separated by the word "or" are hardware versions (must be ordered
as such)
- all outputs are passive unless otherwise indicated
- highC is High Current in/output, namur is in/output to Namur recommendations
