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 :

 R19, R21, R23, R25, R27, R29, R31, R33 : 220Ω/0,5W

 R34, R36, R38, R40, R42, R44, R46, R48 : 220Ω/0,5W (*)

Or mount the resistors to noise-suppress the normally closed contact of

the relay :

 R18, R20, R22, R24, R26, R28, R30, R32 : 220Ω/0,5W

 R35, R37, R39, R41, R43, R45, R47, R49 : 220Ω/0,5W (*)

Next mount the capacitors :

 C1...C8 : 100nF/400V - Type : .1/250A or 15MQ100.

 C9...C16 : 100nF/400V - Type : .1/250A or 15MQ100 (*)

15. Noise suppression of the relay contacts “OPTIONAL !” :

Noise suppression

To use the relay card with 16 relay outputs, mount the components

marked with (*) also (K6714-16).
