I was wondering if anyone knew of any cheap DIN rail mounted Arduino (or similar devices) with 24V digital IO? I am familiar with the Click PLC being about $70 plus the cost of a programming cable ($20). Being an EE and embedded programmer I know arduinos can be bought dirt cheap and are "reasonable" for simple personal projects like mine. For ruggedness, I am hoping to find an enclosure and/or possibly a special purpose arduino-like PCB that has IO built in already. --=20 Jason White --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
