# 12 volt system

#### David Kane

I am working on a mobile application where my available power is +12 VDC. 16 Inputs & 12 Outputs Can anyone suggest a 12VDC PLC? or Is there a "Mobile/Industrial" grade DC to DC convertor to get to +24 VDC?

An obvious consideration is +12VDC to 110VAC convertor to +24VDC for inputs and PLC power, but still use 12 volt outputs.

Dave,

Take a look at automationdirect.com. I have used their DL205 series in mobile applications (railroad maintenance equipment) with much success. They have a 10.2-28.8VDC model, and since this is a modular plc, you can configure the I/O to suit your needs. Their prices are quite reasonable too.

Use a couple of EnT Controllers from www.amt.nb.ca

You might consider FieldPoint I/O found at www.ni.com/fieldpoint. It operates with 12V DC.

I believe the new series of micro/nano PLC's from GE Fanuc can operate at 12 Vdc.

This may be too obvious, but what is wrong with 2 12 volt deep cycle marine batteries hooked up in series? As for charging, many farmers use a solar panel system for electrified fences.
