Zener barriers - Operating instructions
How to select the correct barrier
7.The following points have to be clarified if special field devices
are used.
If the field device is a 4-20 mA transmitter: What load in
Ohms can be connected to the transmitter so that it can at-
tain 20 mA as before
If the field device is a current / pressure converter: What
load can be connected to the controller card so that it can
attain 20 mA as before
If the field device is a transmitter: How high is the load in
the safe area (Typically, resistances of up to 250 Ohm are
used in the controller.).
NEW:
In the near future, a barrier will be available with a
replaceable back-up fuse.
The introduction of a replaceable back-up fuse ahead of the
integrated fuse provides protection against faults which could
occur during the commissioning of the system. It is always
arranged that the outer fuse will respond before the inner, inn-
accessible fuse. The fuses used are specially intended for use
on barriers.
