The Beckhoff Fieldbus Box system is the culmination of the fieldbus concept:


Robust construction allows fieldbus modules to be fitted directly to machines. Control cabinets and terminal boxes are now no longer required.


The modules meet the protection class IP 65, IP 66 and IP 67, are fully casted and thus ideally prepared for use in wet, dirty and dusty working environments. more

Compact Box

Compact Box: Compact Box modules are robust fieldbus stations for 12 different fieldbus systems. They offer a wide range of I/O functionality. All relevant industrial signals are supported.

Coupler Box

Coupler Box: The Fieldbus Coupler Box gathers the I/O data from the extension modules over the interference-free IP-Link fibre optic cable.


PLC Box: The Beckhoff Fieldbus Box with PLC functionality is an intelligent fieldbus module for the decentralised pre-processing of I/O signals. This is a way of removing parts of the application out of the central control system to relieve the CPU and the fieldbus.

Extension Box

Extension Box: The Extension Box modules cover the full spectrum of I/O signals.

IO-Link box

IO-Link box: The IO-Link box modules enable the connection of binary and complex sensors and actuators directly in the field.


Accessories: In addition to pre-assembled cables, field wireable connectors and cables are also available for maximum flexibility.
