Mobile & USB Interface for HART, FOUNDATION fieldbus, PROFIBUS PA

Bluetooth and USB Interface for commissioning parameterization & maintenance for field devices

mobiLink is a mobile and a USB interface for HART, FOUNDATION Fieldbus and PROFIBUS PA.
The Bluetooth and battery operation enables it to be used with handheld host devices such as tablets and smartphones. 
mobiLink can be used in a variety of applications since it is compatible with FDT Frame applications and other major engineering tools. Additionally, It is suited for harsh environments (approved by IECEx and EX for Zone 1).
