Sinusoidal disturbance
The table below shows the EMC compatibility of S7-300 modules in areas subject to
sinusoidal disturbance.
Sinusoidal disturbance Test values corresponds with
degree of severity
RF radiation
(electromagnetic fields)
to IEC 61000-4-3
10 V/m, with 80% amplitude modulation of
1 kHz in the 80 MHz to 1000 MHz range
10 V/m, with 50% pulse modulation at
900 MHz
3
RF conductance on cables
and cable shielding
to IEC 61000-4-6
Test voltage 10 V, with 80% amplitude
modulation of 1 kHz in the 9 MHz to 80 MHz
range
