Tom has the first 24V version
on Steroids, to use a
Huge single load driven by a monstrous IGBT, and it is the Alpha Test.
There are many Regular 24V versions in use. I can not find a decent close up pic. And do not have a completed 24V PCB here to photograph.
So I sort of made one...
The main pic is missing a few parts, the lower right pic has the additional ZD and cap standing up.
I made the "empty holes" a bit too small for the ZD3 and cap. Usually. Sometimes they both fit.
Piggy-Back the cap on the diode if they do not.
When installing parts standing up, orient them so if they twist or turn, they can not short against something they are not already electrically connected to.
And Never determine YOUR proper resistor values from a photo!
I use this online resistor calculator,

OK- I just got the "new post while you were typing warning" and see you do have the 24V parts packets.
The 12V version uses two 5.1V Zeners (they are the same).
The 24V version uses a different value ZD1 and adds a ZD3 and cap in the empty holes.
Also R1 and RX values are changed.
They are in the little 24V parts packet.
