Composition
FieldBarrier for IEC 61158-2 fieldbusses
• High power in the field due to Ex e /
Ex i power feed concept
• Connects up to 4 intrinsically safe
output lines to a non-intrinsically
save fieldbus trunk
• Connection of fieldbus trunk in
increased safety EEx e
• Trunk protection due to short-circuit
current limitation for each output
• Cascadable
• 4 intrinsically safe EEx ia IIC outputs
in accordance to FISCO and Entity
• Installation in zone 1
• Housing IP67 for mounting in the
field
• Switchable integrated fieldbus
termination resistor
• Efficient shielding concept due to
electrical isolation between the
fieldbus trunk and the intrinsically
safe outputs
• Variants with different cable glands
The FieldBarrier connects a non-intrin-
sically safe fieldbus main line to 4 intrin-
sically safe output lines. Due to the
'increased safety' Ex e power feed con-
cept, sufficient power is available to
feed a multitude of field devices. Each
output provides 40 mA. Up to 120 m of
cable can be connected to an output
and operated without a termination
resistor. The FieldBarrier is connected
to a fieldbus according to IEC 61158-2
(MBP) on the trunk side by means of Ex
e connection terminals. The trunk can
be fed to another FieldBarrier of other
fieldbus stations by means of the trunk-
out terminals (cascading). Faults on the
output lines have no negative influence
on the trunk due to the individual short-
circuit monitoring of each output. In
terms of plant reliability it is recommen-
dable to connect one field device to
each output only.
