BEx1 IP67 Ex i
BEx1 IP67 Ex i for Ex zone 1/21
or
Compact IO module for Ex Zone 1/21 with Profinet or Modbus TCP/IP.
The module include busnode, isolating amplifier and 32 intrinsically safe analog and digital IO channels on
smallest space.
The module can be installed directly in Zone 1/21 and connects sensors and actuators from Zone 0/20.
