Hi Kincony,

I know for sure that my load will be below 7 AMPS per channel. Same happens for a H32B-Pro that I have.

Do I need anyway KC868-E16v2 ? 
It would be better not to use internal 7 amp relays of the Server 16 / H32B-Pro?

Please elaborate so I can size my distribution box properly.

Thanks

Yes, use exend relay module KC868-E16v2 is best way.
Server16 inside relay MAX is 7A, for safety , your load current should <3.5A.
