This is my first post here and my background is ME so go easy on me
please. I need to amplify an analog signal that is 0-5V (w/respect to
ground) to be 0-24V (two wires out, not referenced to ground) to drive
a solenoid coil. The problem is my power supply is + and - 12V. I have
two ideas about how to do this:...

This might work.

My Genie opened the envelope and 5V (reed?) relay (sample) dropped on
the floor.

Have fun

what is ME (master in electronics ?) Weird question for a master in
electronics...


Assuming you need an analogic drive (so your solenoid acts proportional
as a gas/liquid ventil or something similar) then you need a simple
power amplifier.
+12V -(-12V) = 24V so you need a B (or AB) class amplifier.
The solenoid must run AC coupled in situation described above, so I
guess it must be a smart one.
If you want two movement directions for the solenoid core, then you
need a DC coupled and +24V and -24V supply with separate ground or a H
bridge and +12V/-12V. The solenoid will be connected between amplifier
output and the ground or between H bridge outputs.

If you need a digital drive (on or off) then you need a simple level
converter from 0V to +12V (that's a NPN followed by a PNP) and solenoid
will be mounted between PNP collector an -12V)

First you need to find exactly what do you want and then ask a complete
and detailed question as someone mentioned.
