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
The modules are extremely small and are thus suitable for use in applications where there is very little space available. The low weight of the Fieldbus Box modules makes them useful in applications where the I/O interface is in motion (e.g. on a robot arm).
All the most important fieldbus systems are supported. This substantially frees electrical design from the particular bus system in use. Fast, flexible reactions to customers‘ requirements are possible. The Fieldbus Box modules are, of course, certified by the respective fieldbus user organisations, and can be combined with Beckhoff Bus Terminals and with devices from third-party manufacturers.
Conventional fieldbuses such as PROFIBUS or CANopen are connected via Coupler Box modules. These are modularly extendable through cost-effective extension modules. The EtherCAT Box modules communicate directly with EtherCAT and require no additional Coupler Box.
The wiring of the fieldbus and of signals is significantly simplified through the use of pre-assembled cables. Wiring errors are minimised and the system setup is finished quickly.
In addition to the pre-assembled cables, field wireable connectors and cables are also available for maximum flexibility.
Combined I/O modules and fine signal granularity lead to low system costs – you only have to buy what you really need.
The wide variety of signal types allows the connection of almost any kind of sensor. The communication modules enable decentralised connection of, e.g., label printers, identification systems or special equipment. The Fieldbus Box range also includes encoder interfaces for displacement and angle measurement. Stepper Motor Box modules are also available.
Sensors and actuators are connected through 8 mm diameter snap type or through screw type connectors (M8 or M12). The snap type connectors lock in place positively, forming a vibration- proof connection, while the screw type connectors offer the advantage of high resistance to being pulled out.
The Fieldbus Box devices behave very much like the Beckhoff Bus Terminals – this means that the ideal distributed peripheral device can be used, whatever the particular application.
In the EtherCAT Box version the box modules have a direct EtherCAT port. Virtually all sensors and actuators can be connected to the control system directly via the 100BASE-TX. XFC boxes are available for additional requirements, e.g. time stamp inputs.
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: 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.

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