8650 AirLINE Ex Electropneumatic Automation System

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.


  • For use in potentially explosive areas (Zone 1/21)
  • Developed in cooperation with Siemens
  • Electrical connection via PROFIBUS® DP-is, electrical I/O functions via Siemens SIMATIC ET 200 iSP™ module
  • NEW REV.2 makes new integrable functions like pressure sensor or pressure switch possible
