What is possible?
The devices of the SCALANCE X100 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 X104-2
● SCALANCE X106-1
● SCALANCE X112-2
IE switches with the suffix PoE also allow the supply of power to end devices over Ethernet
cables with Power-over-Ethernet complying with 802.3af.
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 load
s.
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 exampl
e, the Dehn Blitzductor
BVT AVD 24 V type no. 918 422 or a comparable protective element.
