A fundamental component for automation

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 Bus Terminal principle

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.

Free signal mix

The fine granularity of the Bus Terminals enables bit-precise composition of the required I/O channels. The digital Bus Terminals for generating and processing binary signals are designed as 2, 4, 8 and 16-channel terminals or with up to 64 channels as terminal modules. The 16-channel HD (High Density) version combines 16 digital input and output channels into a standard terminal housing with a width of just 12 mm.

The analog input terminals for the acquisition of analog signals from the field can process a wide range of measured variables, such as current, voltage, temperature and resistance. In addition to the signal type, the terminals also differ in signal resolution and measuring accuracy. In the analog output range, the standard signals of ±10 V, 0…10 V, 0…20 mA and 4…20 mA are consistently available as 1, 2, 4, or 8-channel version in a standard housing.

The Bus Terminal portfolio also offers comprehensive solutions for drive control, the evaluation of various encoder interfaces and for special measurement applications, such as power measurement.

Fieldbus-neutral communication

The Bus Terminals form a fieldbus-neutral I/O system in wich the Bus Couplers act as an interface between fieldbus and the Bus Terminals. Bus Couplers are available for the following bus systems:

  • EtherCAT, the high-speed, real-time Ethernet fieldbus
  • Lightbus, the fast fiber-optic fieldbus
  • PROFIBUS DP/FMS, according to the European standard EN 50170
  • Interbus, which has been on the market since 1987
  • CANopen, the multimaster in the actuator/sensor area
  • DeviceNet, the device bus with CAN technology
  • Modbus, the open fieldbus
  • CC-Link, the fieldbus for the Asian market
  • SERCOS interface, the drive technology bus
  • RS232/RS485, the network for low-cost solutions
  • Ethernet TCP/IP, the network bus
  • Ethernet/IP, the Industrial Ethernet solution from ODVA
  • PROFINET, the Industrial Ethernet solution from PNO

With the master terminals, fieldbus functionalities are available in form of a standard Bus Terminal. This is particularly advantageous for bus systems that are integrated as a subsystem in a higher-level system. This means that only one system is required for the subsystem and the higher-level bus interface. Master terminals are available for the following bus systems:

  • AS-Interface, the sensor/actuator bus for the lower control level
  • IO-Link, the interface for intelligent sensors and actuators
  • KNX/EIB, DALI, MP-Bus, M-Bus, SMI and Enocean: the communication standards in building automation

Flexible connection technology

With various connection options, the Bus Terminal system allows optimal adaptation to the relevant application. In the KLxxxx Bus Terminals, electronics and connection level are located in one housing.

In contrast, the KSxxxx Bus Terminals have a pluggable wiring level, so that in case of service, the entire wiring can be removed as one connector from the top side of the housing.

Economic efficiency

With the Beckhoff Bus Terminals, control cabinets and terminal boxes can be built more economically. The Bus Terminals perfectly fit the terminal boxes' dimensions and can be easily plugged onto a standard profile rail. The contacts are made as the terminal clicks into place, with no further action. Each terminal remains individually exchangeable. A clear front connection panel with a status display and the insertable contact labeling ensure clarity on-site. The flexible conductor connection technologies allow the usage of the Bus Terminals in almost every application without additional wiring work. The 3-wire technology, optionally supplemented by a protective conductor connection, enables the direct link of sensors and actuators to the terminal.
