Fieldbus is a digital network allowing
usage of existing 4-20mA cables, avoiding costly re-wiring. Fully certified
by passing ITK, this device has passed several Interoperability
requirements over a broad range of hosts. When combined with DeltaV
and using the power of PlantWeb, those devices provide intelligent alerts
allowing accurate device maintenance and service.
