i'm using the GEO +/- 12vdc dual supply regulated, and just want to know , if i connect a board or a led on the +12vdc can i use the ground from the wall transformer ( the ground that goes in the dual supply regulated board) or i MUST use the ground that come's out of the board....
exemple:
+ 24vdc -> -> -> PCB DUAL -> -> -> +12vdc
-> -> -> SUPPLY -> -> -> ground
ground -> -> -> REGULATED -> -> -> -12vdc
^ ^
this ground or this ground
i wish that i explain clearely my question.... ;D
thank's

Use the ground that you are using to measure the +12v from. The ground on the output of the regulator board.
