Hello Guys ![:) :)](/media/kunena/emoticons/smile.png)
I have bought a 7i95 Mesa Card for retrofitting my CNC-Mill.
I had to buy this card, because all other cards are not in stock.
I read the manual and wired the inputs for some tests in LinuxCNC. This worked great.
Now I want to wire the Outputs, but I am not sure how to do this. In manual they were described as Out0- and Out0+.
Could you please explain me, how to connect this outputs? I don't want to damage the card, because it was the last one in the shop
.
Thank You
Kind Regards
Matthias

they are isolated outputs.
basically, think of them like a switch... you wire either the + or - to the load and depending if the + is wired to the load the - would go to zero V
or in the - is wired to the load, the + would be wired to the positive voltage (uo to 36v)
each output is independent so they can each be wired differently.

Thank you for your fast answer ![:) :)](/media/kunena/emoticons/smile.png)
Can they switch up to 36V or they can only switch 5V?

www.mesanet.com/pdf/parallel/7i95man.pdf
PDF page 6 of the discription:
Six 36V 2A isolated outputs allow sinking, sourcing
combinations of both
PDF Page 42:
ISOLATED OUTPUTS
OUTPUT SWITCHED VOLTAGE 0V +36V
OUTPUT SWITCHED CURRENT ---- 2A
OUTPUT RESISTANCE ---- 75 mOhm
OUTPUT ISOLATION VOLTAGE ---- 100 VDC
MAXIMUM OUTPUT FREQUENCY ---- 5 KHz
mesa manuals are very comprehensive (sometimes it takes a while to digest + understand how much info is provided).

Thank you, with your help now I found it in the manual
