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.
