4.1 Purpose
What is possible?
The IE switches of the SCALANCE XB-000 product line allow the cost-effective installation of
Industrial Ethernet bus and star structures with switching functionality.
With the following IE switches, there are also electrical/optical media transitions:
• SCALANCE XB004‑1
• SCALANCE XB004‑2
• SCALANCE XB004‑1LD
• SCALANCE XB004‑2LD
• SCALANCE XB004‑1G
• SCALANCE XB004‑1LDG
Note
It is not possible to use IE switches of the SCALANCE XB-000 product line in a redundant ring
because they do not support redundancy.
Note
If devices are supplied over long 24 V power supply lines or networks, measures are necessary
to prevent interference by strong electromagnetic pulses on the supply lines. These can result,
for example, due to lightning or switching of large inductive loads.
One of the tests used to attest the immunity of these devices to electromagnetic interference is
the "surge immunity test" according to EN 61000-4-5. This test requires overvoltage protection
for the power supply lines. A suitable device is, for example, the Dehn Blitzductor BVT AVD 24 V
type no. 918 422 or a comparable protective element. An example of a suitable device for AC
operation is the Blitzductor BXT ML2 BD S 48, art. no. 920 245, in combination with the basic unit
BXT BAS, art. no. 920 300, or a comparable protective element.
