Industrial PCs construction and features

Virtually all industrial PCs share an underlying design philosophy of providing a controlled environment for the installed electronics to survive the rigors of the plant floor. The electronic components themselves may be selected for their ability to withstand higher and lower operating temperatures than typical commercial components.
