BEx Remote IO Valve Terminal

BEx Remote IO Valve Terminal

With this 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 Include:

  • 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

User 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.
