> The user manual of the C-Control-1 V2 (M-Unit and station ) warns that the digital ports may never deliver more than 20mA.|
That is 20mA per port, then.
> Question 1: If all 8 digital ports feed the C-Control relays amplified by transistors, are we above 20 mA ?
Depends, and irrelevant. 20mA per port may not be exceeded.
> How many activited ports before reaching 20 mA ?
Depends, and irrelavant.
> Question 2: What if the ports deliver more than 20mA together ? Dammage ?
If "the ports" deliver more than 20mA alltogether, while not any single port delivers more than 20mA, then you're working within the specification of "20mA max per port".
If a single port delivers more than 20mA then damage probably will happen.
> Question 3: If nobody can answer question 1, who is ready to volunteer to activate one by one his output ports to feed the amplified Conrad relays ? And then tell on the forum when his C-control blew up...
Yeah, right! ;-)
