FOUNDATION™ fieldbus I/O is a modular subsystem that communicates digitally with field devices, increases your input/output capacity, and gives you access to more information about your process than conventional I/O subsystems. It greatly enhances device diagnostics that affect your control strategy and alerts operators to device malfunctions. If you want an efficient, economical, and secure process control system, use DeltaV™ FOUNDATION fieldbus I/O.
