I think it depends where you want to use it for. If you want to control a machine, like the topic starter, you need a dedicated PLC. Like I told him before. But, if you use him to get extra information about your process, with additional
extra sensors. It will not harm anything, at least until someone get a inspection??
And there are product out there that are suitable for a Industrial use, like the
BeagleBone Black Industrial. But with the same remarks about controlling machines.
And the DIN rail mount could also be ideal for home automation
