The manual wiring example shows external power wired to EXT+24 terminal, with switched ground to activate inputs.
I need to supply 24V to activate the input.
On page 24 of the manual, it shows switched 24v going to the input, but doesn't show pin numbers in the example
The manual also lists jp4 pin 1 as DIG, Digital input ground, but no example of use.

Would this work: Ground to DIG and switched 24VDC to DI1?

Thanks, I really don't want to fry anything.
