BEx1 valve box

3 in 1 solution for Ex area

Powered by FESTO and Exepd

BEx Remote IO valve terminal  

With the 3 in 1 solution, the plants and machine builders have a decentralized and compact Remote IO valve terminal for the first time
for controlling pneumatic actuators for the hazardous area Zone 1/21.

Applications

  • Paint shops

  • Pharmaceutical plants

  • Chemical plants

  • Tank farm
  • Bulk materials handling systems

  • Mixing / grinding plants

  • Industrial heating / cooling systems

  • Sewage treatment plants and much more

Integration

  • 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.

Installation scheme BEx1 Remote IO valve terminal

Customer benefits

Compact - Simple - Fast

 

  • 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.
