French term (edited): organe de contrôle moteur

Asker, it might be helpful for you to give us rather more of this "long list of elements/components that should be integrated into a computerised system" — I suspect that what you have here is not really part of the computer system per se, but rather, one of the peripherals, used in this case to control motors. Presumably, in this case, literal, physical (electric) motors that are used as part of the pharmaceutical manufacturing process. It may be possible to tell this by reference to other items on the list.

'organe' is a favourite catch-all sort of word in FR, and even though we do also use 'organ' in EN, it is much less common, and I feel that here simply 'device' will fulfill the equivalent role.

This use of 'device' of course equates more to the notion of 'dispositif' than to 'composant', which can be another of its meanings in FR.

OK, so now we have that vital extra context that confirms my hunch:

« les composants industriels propres aux activites de terrain : ... »

So here we are not talking about a part of the actual computer itself, but rather, the peripherals involved in the actual industrial process itself.

Had we had this context from the outset, I would have give my suggestion a higher confidence level.
