What is a "5x 24volt signal"?

5x voltage regulators or voltage dividers?

More info needed as to the present signal versus desired signal.

For each of the 5 signals at 24 volts, Use a resistance potentiometer with two equal value resistors R, tight tolerance.

Assumed conditions :-

24 volt source has low resistance compared to R, < R/100.

"12 volt" load has high resistance > 100R

Error of ~1.5% in reduction ratio compared to 2 to 1 is OK.

Do you mean logic signals (on/off) or analog signals e.g. process temperature??
