3.1.6 Ferrite core
Use of ferrite cores is effective in reducing the conduction noise in the band of
about 10 MHz and radiated noise in 30 to 100 MHz band.
It is recommended to attach ferrite cores when the shield of the shielded cable
coming out of control panel does not work effectively, or when emission of the
conduction noise from the power line has to be suppressed
core used in our tests is the TDK-made ZCAT3035.
Install the ferrite core immediately before pulling the cables out of the panel. If the
installation position is not appropriate, the effect of ferrite may be diminished.
1 To response with CE(EN61131-2/A12), make sure to mount 2 or more
ferrite cores onto the power supply line. The mounting position should be as
near the power supply module as possible. Use the ferrite core of
ZCAT2235-1030A.
Ferrite core
Type: ZCAT 2235-1030A(TDK ferrite core)
N/A
Use a CE-compliant 24VDC power supply in the control panel.
Make sure to short and ground the LG and FG terminals.
