I want to use the Pogrammable Logic Controller in a vehicle application project, but the vehicle has a 12volt battery, and the PLC requires 24volt DC. I don't want to use an inverter to get up to 240v AC, and then a rectified transformer to get back down to 12v DC, there must be a way to get from 12v DC to 24v DC by a more direct route. Does anybody know of a workable and cheap solution? PLCs consume very little power themselves, their inputs and outputs can use the vehicle 12v DC.

yes use a voltage doubler plenty of sites on net that shows how its done with jus a few cheap components about £5 would cover it.

Look into power converters.
Additional information.
a) Transformers will not work with direct current (DC)
b) The suggestion of a voltage doubler given below by one_browser is what you need (see ref 2). It will cost less than 5 ponds probably about $2.

A small step-up transformer would do the trick.
