I made this little schematic, sorry but i want to stay 100% secure (sorry maybe i doesn't understand something because I'm not native English speaker).

I want to use the pins 12 and 25 of digital inputs (11+ and 11-).

It's correct put 11+ (+24v) in touch plate and 11- (pin 25) to -24V power suppy? (all - csmio pins are wired manually to -24V )
