Product Advantages and Features


1.High - expandability

It can connect the SERCOS bus system with the electronic terminal block. One unit consists of one bus coupler, any number of terminals from 1 to 64, and one end - terminal. Through the K - bus extension technology, it allows up to 255 bus terminal modules to be connected to one bus coupler.


2、Support for multiple transmission rates

The data transmission rate is 2/4/8/16 Mbaud, which can be adjusted by the configuration switch. Compared with some similar products that only support 2 Mbaud and 4 Mbaud, it has more flexible transmission speed options.


3、Powerful signal processing ability

It can process a large number of digital and analog peripheral signals, with 1020 input/output digital peripheral signals and 254 input/output analog peripheral signals.


4、Automatic identification and configuration

The bus coupler can automatically identify the connected terminals and automatically generate the affiliation of the input/output to the bytes of the process image, simplifying the system setup and debugging process.

5、Compliance with international standards

The bus interface complies with the FSMA standard (IEC 872 - 2), and the SERCOS bus has complied with the international standard IEC 61491 since 1995, with good compatibility and versatility, suitable for a variety of CNC equipment.


6、Ring - shaped bus topology

It supports the ring - shaped bus topology, which can operate up to 254 stations. This topology has high reliability. When a certain node fails, it usually does not affect the operation of the entire system.


7、Convenient parameterization

Parameters can be set through the SERCOS interface, and the KS2000 configuration software can also be used to set the required parameters on the PC. The bus terminal can permanently store or safely store the parameter settings in case of failure.


8、Strong environmental adaptability

The operating temperature is 0…+55°C, the storage temperature is - 25…+85°C, the relative humidity is 95% without condensation, the vibration/shock resistance complies with EN 60068 - 2 - 6/EN 60068 - 2 - 27, the EMC immunity/radiation complies with EN 61000 - 6 - 2/EN 61000 - 6 - 4, and the protection level is IP20, which can adapt to a variety of industrial environments.

Product Application Scope


1、CNC Machine Tools Field

The SERCOS bus complies with the international standard IEC 61491 for CNC machine tools. BK7520 can be well - adapted to CNC machine tools, which can precisely control the movement of each axis of the machine tool and achieve high - precision machining operations. It is often used in various CNC lathes, milling machines, grinding machines and other equipment.


2、Automated Production Lines

 In the automated production lines of automobile manufacturing, electronic manufacturing, etc., it can connect a variety of sensors and actuators to achieve precise control and monitoring of the production process. For example, it is used for the motion control of robots on the automobile assembly line and the material conveying and positioning on the electronic product production line.


3、Metallurgical Industry

It can be applied to the control of various equipment in the metallurgical production process, such as the feeding system of the blast furnace, the temperature and liquid - level control of the steel - making furnace, and the speed and thickness control in the steel rolling process. It can adapt to the harsh environments such as high temperature and high dust in the metallurgical site.


4、Metallurgical Industry

It can be applied to the control of various equipment in the metallurgical production process, such as the feeding system of the blast furnace, the temperature and liquid - level control of the steel - making furnace, and the speed and thickness control in the steel rolling process. It can adapt to the harsh environments such as high temperature and high dust in the metallurgical site.


5、Energy Field

It is also used in energy - related scenarios such as power production and substation automation. It can be used for the control system of the generator set, the control of the switching equipment in the substation and the monitoring of power parameters, etc., to realize the automatic control and management of the energy production and distribution process.


6、Paper - making and Printing Industry

It can be used for the control of the pulp preparation, paper forming and winding links in the paper - making production line, as well as the ink supply, printing speed and register accuracy control of the printing press, which helps to improve the quality of paper and printed products and the production efficiency.



Product Description


1、The Beckhoff BK7520 is a SERCOS II bus coupler specially designed for industrial automation scenarios. As a core connection hub between the SERCOS bus system and electronic terminal blocks, it plays a key role in signal transmission, equipment linkage and system integration. It adopts an overall compact terminal housing design, with the housing material being polycarbonate, and is equipped with a 35mm DIN rail mounting method (compliant with EN 60715 standard and with a lock). This design can flexibly adapt to the installation layout in different industrial control cabinets, saving space while ensuring stable installation.

2、The device is equipped with intuitive signal LED indicators, which can feedback the bus operation status, power on/off and terminal connection status in real time, facilitating staff to quickly troubleshoot faults and judge the equipment working conditions. In terms of wiring design, it supports three wiring types: solid conductors, flexible conductors and ferrules, and adopts a screwdriver-actuated spring-type wiring method. The wiring cross-section covers 0.08-2.5mm² (for solid wires and stranded wires) and 0.14-1.5mm² (for wires with ferrules), with a required wire stripping length of 8-9mm. This design balances wiring convenience and connection stability, meeting the diverse wiring needs of industrial sites.

3、From the perspective of safety and compliance, the BK7520 has obtained multiple international certifications such as CE, UL and ATEX, with an explosion-proof mark of II 3 G Ex nA IIC T4 Gc. Its electrical isolation level reaches 500V (covering power contacts, power voltage and field bus), which can effectively isolate electrical interference in industrial environments and ensure the safety of equipment and personnel. In addition, the device supports flexible configuration and safe storage of parameters. Parameters can be set either directly through the SERCOS interface or on the PC terminal via the KS2000 configuration software. Moreover, the bus terminal can store parameters permanently or safely in case of faults, avoiding system restart failures caused by parameter loss and further improving the reliability and maintenance efficiency of the device operation.
