Compact - Simple - FastBEx Integration valve
  • Central Ethernet connection, central compressed air connection
  • The compact housing enables optimal decentralized installation in the system and guarantees short distances to the sensors and the pneumatic actuators.
  • No compressed air tubing inside the housing.
  • Cost savings and less installation effort
The ATEX certified system in the field housing is designed for installation in Zone 1/21
 
The BEx1 Remote IO valve terminal combines bus nodes, isolating switching amplifiers, intrinsically safe IO channels and the pneumatic valve terminal.
  • The Ethernet connection (Profinet or Modbus TCP / IP)
    is executed in increased safety Ex e.
  • Ex media converters or fieldbus couplers in the safe area are not required and the full Ethernet performance can be used.
  • No IO modules required on the PLC
  • The BEx1 module does not have to be parameterized or configured and behaves transparently in the control I / O.
