Customer value
▪ For optimal combining of intrinsically safe signals in the lower field level.
▪ Allows very short cable lengths to the solenoid valves and initiators which means significant cost and
time savings during installation and maintenance.
▪ The Ethernet connection is designed with increased safety. An Ex media converter in the safe area is
no longer required and the full Ethernet performance can be used.
The ATEX certified system with field enclosure is designed for installation in Zone 1/21 and connects sensors and actuators
from Zone 0/20.
BEx1 includes busnode, isolating amplifier and 32 intrinsically safe analog and digital IO channels on smallest space.
