7iA0 outputs was created by Dennie
Hey folks, I'm a german guy who lives in Paraguay. At first I want to say thank you for LinuxCNC and all the projects around
it. Wow, my head is exploding because of learning all the stuff.
I am currently retrofitting an Edel Micromat 205HS CNC nibbler.
I want to buy a 7i97t because of the analog Perma Drive drivers and servos (A,A/,B,B/,0,0/, +-10V).
For all the sensors, switches and contactors I'd like to buy a 7iA0.
My question to you would be:
The machine has originally I/O cards from Labod and the 24V power supply for the output mosfets can be switched off with E-
Stop.
I want to do the same with the 7iA0 but I do not understand the outputs in the manual.
There it says
PIN 1 OUT -00-
PIN 2 OUT -00+
PIN 3 OUT -01-
PIN 4 OUT -01+
and so on.
Can I connect 24V+ to PIN 2, 4,... and so on so the card connects this PINs to PIN 1, 3,... and so on? Or is it the
other way round? As to speak, does the card connect the -PIN with the +PIN next to it when an output is switched on? If that's
the case, do I connect 24V+ to 2, 4,... or to 1, 3,...?
Thank you in advance for your help.
Greetings
Dennis

PIN+ must always be the most positive pin.
PIN+ is the NMOS drain connection and PIN- the NMOS source connection.
So yes:
Sourcing connection:
+24V --> PIN+ --> PIN- --> load --> 24V Common
Sinking connection:
+24V --> load --> PIN+ --> PIN- --> 24V Common.

Great, thank you. So I will not burn the card nor do I have to follow the traces to figure it out myself. <3
Time to go shopping in the Mesa store.
May I ask you another question?
Did I understand it correctly that the 6 outputs on the 7i97t share one 24V+ (for example) which comes from the other connector?
