13. Noise suppression of the relay contacts “OPTIONAL !” :
At the standard module K6714 as well K6714-16 have you the opportunity to
noise-suppress every relay contact.
First : mount the resistors to noise-suppress the normally open contact
of the relay :
q R19, R21, R23, R25, R27, R29, R31, R33 : 220O/0,5W
q R34, R36, R38, R40, R42, R44, R46, R48 : 220O/0,5W (*)
Or mount the resistors to noise-suppress the normally closed contact of
the relay :
q R18, R20, R22, R24, R26, R28, R30, R32 : 220O/0,5W
q R35, R37, R39, R41, R43, R45, R47, R49 : 220O/0,5W (*)
Next mount the capacitors :
q C1...C8 : 100nF/400V - Type : .1/250A or 15MQ100.
q C9...C16 : 100nF/400V - Type : .1/250A or 15MQ100 (*)
To use the relay card with 16 relay outputs, mount the components
marked with (*) also (K6714-16).
