4.4 Input/output connections
• IFC 300 converters are available in versions with intrinsically safe (Ex i) or non-intrinsically
safe (non-Ex i) inputs/outouts (I/O). Details of both versions (CG. no's and connection of
terminals) are listed in the IFC 300 handbook.
• The versions with non-Ex i I/O are listed in the IFC 300 handbook (title: alterable input/output
versions). The version basic I/O is also with non-Ex i I/O. The electrical data of the I/O circuits
with non-Ex i I/O are:
U
n
< 32 VDC and I
n
≤100 mA.
• The versions with Ex i inputs/outputs are listed in the IFC 300 handbook (title: Fixed, non-
alterable input/output versions), except the IFC 300 version basic I/O, last digits of CG. no.
100. This version is always with non-Ex i I/O.
The electrical data of the versions with Ex i I/O are listed below.
The following signal I/O connections are available as intrinsically safe:
The I/O circuits titled “Ex i I/O” and “Ex i Option” are always provided with type of protection
Intrinsic Safety (Ex ia). The I/O-circuits “Fieldbus I/O Profibus-PA” as well as “Fieldbus I/O
Foundation Fieldbus” can be provided with type of protection Intrinsic Safety.
