Be a little carful here. it's not just that you want 12VDC, you also need to pay attention to temperature and vibration specifications when using controllers on a vehicle. Many of the low cost micro PLCs will not do well with that. The Teco SG2 for example is only rated 70C (158F) storage, many of the others are far less, but vehicles in the sun can reach much higher air temps. You don't likely need to worry about the operating temperature that much, because if it is operating you will have some form of climate control. The problem is with damaging the controller when the vehicle is parked in the sun. When the outside temp is 80-100F, the interior temp can be as high as 172F (78C) if exposed to the sun, so you want something that can handle at least 85C (185F) storage temperature. Also, you will want something that is rated for at least 2G of acceleration and 30G of shock, the Teco and others listed are not rated that high at all. It's safer to assume that if a supplier fails to list their environmental limitations, the lack of it indicates they may have something they don't want known. RTFM before you buy.
The IFM unit linked to will meet those specs, but requires CAN programming, not typical of industrial logic if you are not familiar with it.
The only pico type PLCs, those that program like PLCs that is, that I am aware of that are available with those kinds of environmental specs are the Siemens LOGO! Extended Range version (which is also brand labeled as Idec), and the AB Micro 810. Both are available with 12VDC input.
