BEx Remote IO Module
Zone 1 / 21 or 2 / 22
Compact Remote IO modules for Ex Zone 1/21 or Zone 2/22 with Profinet or Modbus TCP/IP
The modules include busnode, isolating amplifier and 32 intrinsically safe analog and digital IO channels on smallest space.
BEx1 module can be installed in Zone 1/21 with certified Ex e enclosure and connects sensors and actuators from Zone 0/20.
BEx2 module can be installed in Zone 2/22, in a suita-ble housing according EN 60079-7:2018 with a protec-tion degree of at least IP 54 and connects sensors and actuators from Zone 0/20.

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.
