Zone 1 Remote I/O

BEx Remote IO Module for Ex 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 suitable housing according EN 60079-7:2018 with a protection degree of at least IP 54 and connects sensors and actuators from Zone 0/20.
