Please see circuit attached...
This tricks me because there is an overall voltage drop of 24V across two diodes. The ground is in the middle. The way this will work with the rest of the circuit though (my on-going PID project), is that either of the diodes can be removed to make the input unipolar (either positive or negative). So I am trying to figure out whether I should be looking at the 24V drop and both diodes should have a value of 27 or 30, or I should be looking at individual half-circuits and then the diodes would have a much lower value of 16 or 18? But would that not affect circuit when both both diodes are in or because the ground is in the middle, each diode should never "see" the 24V?
Any input is, as always taken in with gratitude.
