Industrial equivalent of rapid prototyping hardware
Generally something like a PLC (programmable logic controller) that comes with housings, power supplies, is hardened against an industrial environment and will still be serviceable or replaceable in a decade or three. 

The costs of downtime, safety issues and engineering time are such that 'toy' devices like the ones you mention would generally hold no attraction in most such applications- the life cycle costs are lower for professional solutions. 

That does not mean that there are not plenty of such devices deployed in corporate R&amp;D labs and startups - sometimes it's quite appropriate for hacking together a test or a proof-of-concept, and not every company has the budget to purchase a rack full of equipment to explore a new idea or set up a temporary experiment.
