The Beckhoff Bus Terminal system, consisting of electronic terminal blocks, is a fundamental component for automation technology. The open, fieldbus-neutral I/O system is connected to more than 30 fieldbus and Industrial Ethernet systems, such as PROFIBUS, PROFINET, CANopen or BACnet, using Bus Couplers or master terminals.
With a wide range of I/O components for connecting all commercially available sensors and actuators, Beckhoff covers the communication routes between the control system and the field level, thus completing its universal control and drive solution. The focus here is on the simple integration of the open control technology. The product portfolio includes more than 1,000 Bus Terminals for over 100 different signal types.
The Beckhoff Bus Terminals are used in various industrial sectors – from machine construction to building control systems – and have successfully proven themselves due to the simple system planning, wiring, commissioning and maintenance.

The Beckhoff Bus Terminals form an open and fieldbus-neutral I/O system consisting of electronic terminal blocks. The connection between the Bus Terminals and the fieldbus is provided by Bus Couplers, which are available for PROFIBUS, CANopen, DeviceNet, and many other common fieldbus systems.
Besides standard I/O signals, the product portfolio also includes safety I/Os for the combined use of safety functions and I/O technology in one system. Furthermore, Bus Terminals are also available for special tasks in building automation or for implementing drive solutions.
All components can be simply plugged onto the DIN rail in the control cabinet or terminal box. Power supply, communication and field voltage distribution are automatically provided via internal terminal contacts when they click into place.
