Bürkert AirLINE Ex – Electropneumatic Automation System for Use in Potentially Explosive Areas

AirLINE Ex Type 8650 is a modular electrical and pneumatic automation system that controls complex processes in potentially explosive areas (Zones 1/21). The protection class “intinsically safe” (Ex i) of electronic modules and valves allows modules to be replaced during operation. With the modules of the cooperation partner Siemens, Bürkert offers electrical, analogue and digital I/O functions for use in Zone 0.
