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.
