Product Advantages and Features

1、Standardized Mechanical Structure

The housing is made of engineering plastic material with a flame retardant rating compliant with UL 94 V-0, featuring both lightweight and impact resistance. Its dimensions strictly follow the unified specifications of Beckhoff's bus terminal system (51mm×100mm×69mm, width×height×depth), allowing seamless installation with other terminal modules of the same series and maximizing space utilization on the DIN rail.

2、Clear Status Indication Design

Equipped with multiple groups of LED indicators, corresponding to power status (Power), PROFIBUS-DP bus communication status (Bus), module connection status (Module), and fault alarm status (Error) respectively. Different colors (e.g., steady green for normal, flashing red for fault) and blinking modes can intuitively reflect the equipment's operating status, facilitating on-site personnel to quickly locate problems.

3、Wide-Range Power Input

Supports a DC 24V±20% power input range, which can adapt to power voltage fluctuations in industrial on-site environments and avoid equipment shutdown caused by unstable voltage. It also has overvoltage and overcurrent protection functions to prevent damage to internal circuits due to abnormal power supply, extending the equipment's service life.

4、Configurable Bus Address

The PROFIBUS-DP bus address (usually ranging from 0 to 126) can be flexibly set via the DIP switches on the device or software tools. Without relying on complex hardware modifications, the device number can be adjusted according to the address allocation requirements of the on-site bus network, simplifying the address planning process during multi-device networking.

5、Hot-Swappable Compatibility (in Specific Scenarios): When matched with specific series of Beckhoff bus terminal modules and meeting system safety specifications, it supports hot-swapping of downstream connected terminal modules (the coupler itself needs to remain powered on). Faulty modules can be replaced without interrupting the operation of the entire bus system, reducing downtime during production.

Product Application Scope

1、Discrete Manufacturing Automation

It is suitable for discrete manufacturing scenarios such as auto parts production, electronic device assembly, and mechanical processing. In these scenarios, production lines need to realize communication between PLCs and distributed I/O modules (e.g., digital input/output modules, analog acquisition modules) via the PROFIBUS-DP bus. The BK2000 can connect KL/EL series terminal modules to the PROFIBUS-DP network, enabling functions like on-off control of production equipment and status monitoring—for example, spindle start-stop signal acquisition of machine tools and sensor data transmission in assembly lines.

2、Process Industry Monitoring Systems

In process industries such as chemical engineering, petroleum, and food & beverage, real-time acquisition and control of continuous process parameters (e.g., temperature, pressure, flow) are required. The BK2000 can be paired with temperature measurement modules (e.g., KL3062) and analog input modules (e.g., KL3314) to transmit process data from on-site sensors to process control units (e.g., DCS) via the PROFIBUS-DP bus, while receiving control commands to drive actuators (e.g., valves, pumps), meeting the requirements of process industries for data real-time performance and stability.

3、Smart Equipment and Machine Tool Field

It is applicable to smart equipment such as CNC machine tools, robot workstations, and automated assembly machines. Such equipment usually requires multiple sets of distributed I/O interfaces to connect to the bus system. The BK2000 can flexibly expand the number of terminal modules (supporting up to 32 modules), adapting to the equipment's needs for processing different types of signals (e.g., pulse signals, high-speed counting signals)—for example, control of pneumatic components in robot end effectors and position signal feedback of CNC machine tool axes.

4、Energy and Infrastructure Monitoring

In infrastructure scenarios such as power distribution, water treatment, and smart buildings, remote monitoring of distributed electrical equipment (e.g., power distribution cabinets, water pumps, fans) is necessary. The BK2000 supports a wide operating temperature range of -25 °C ~ +60 °C and is equipped with overvoltage and overcurrent protection functions, enabling stable operation in complex environments such as outdoor distribution boxes and basements. It realizes the acquisition of equipment operating status (e.g., current, voltage) and the transmission of remote control commands.

5、Retrofitting and Upgrading of Small and Medium-Sized Automation Systems
For old automation systems that originally use the PROFIBUS-DP bus but have insufficient I/O interfaces or single-type terminal modules, the BK2000 can serve as an "expansion bridge". There is no need to replace the existing PROFIBUS-DP master (e.g., PLC); by only adding the BK2000 and supporting terminal modules, the number of I/O points can be expanded, and special function modules (e.g., high-speed counting, communication modules) can be supplemented, reducing the cost and complexity of system retrofitting.

Product Description

1、Beckhoff BK2000 is a PROFIBUS-DP bus coupler specifically designed for industrial automation bus systems. As a core component of the Beckhoff Bus Terminal System, it is primarily positioned as a bridge between the "PROFIBUS-DP bus" and "Beckhoff KL/EL series bus terminal modules". It enables the conversion, transmission, and centralized management of fieldbus protocols and terminal module signals, providing stable distributed I/O expansion capabilities for industrial control systems.

2、In terms of hardware design, the BK2000 adopts a standardized compact structure with dimensions of 51mm×100mm×69mm (width×height×depth). Its housing is made of engineering plastic with a flame-retardant rating compliant with UL 94 V-0, featuring both impact resistance and lightweight properties. It can be directly mounted on a 35mm DIN rail (in line with EN 60715 standard) and seamlessly fits with other terminal modules of the same series, maximizing the use of space inside control cabinets. The front of the device is equipped with multiple groups of LED indicators with clear functions, corresponding to power status (Power), PROFIBUS-DP bus communication status (Bus), terminal module connection status (Module), and fault alarm status (Error) respectively. Through different colors (steady green for normal operation, flashing red for faults) and blinking patterns, it intuitively reflects the device's operating conditions, facilitating on-site personnel to quickly troubleshoot issues.

3、In terms of functional configuration, the BK2000 natively supports the PROFIBUS-DP V0/V1 protocol. The communication rate can be automatically adapted or manually set within the range of 9.6 kbps to 12 Mbps, and the bus address can be flexibly configured (range 0-126) via DIP switches on the side of the device or dedicated software, allowing easy integration into existing PROFIBUS-DP bus networks. A single coupler can connect up to 32 Beckhoff KL/EL series terminal modules, compatible with various types of modules such as digital, analog, temperature acquisition, and high-speed counting modules, meeting the diverse signal acquisition and control needs of industrial sites. In terms of power supply, it supports a wide input range of DC 24V±20%, which can adapt to power voltage fluctuations in industrial environments. Additionally, it has built-in overvoltage and overcurrent protection circuits to prevent damage to internal components caused by abnormal power supply, extending the device's service life.

4、In terms of environmental adaptability and stability, the BK2000 offers industrial-grade protection performance. It has an operating temperature range of -25°C to +60°C, a storage temperature range of -40°C to +85°C, and a relative humidity tolerance of 5% to 95% (non-condensing). It also complies with IEC 60068-2-6 (vibration resistance) and IEC 60068-2-27 (shock resistance) standards, enabling stable operation in complex environments such as machine shops, chemical plants, and outdoor distribution boxes. Furthermore, some models have obtained ATEX and IECEx explosion-proof certifications, making them suitable for hazardous industrial scenarios with explosion-proof requirements.

5、In terms of debugging and maintenance convenience, the BK2000 supports two parameter configuration methods: one is to directly issue configuration commands through a PROFIBUS-DP master device (such as a PLC or industrial computer); the other is to use the Beckhoff KS2000 configuration software to complete parameter settings (including communication rate, bus address, and module association) on a PC, without the need for complex hardware debugging. Meanwhile, under the premise of meeting system safety specifications, hot-swapping of downstream connected terminal modules is supported. When replacing a faulty module, there is no need to interrupt the operation of the entire bus system, significantly reducing production downtime. In terms of compliance, the BK2000 has obtained international certifications such as CE, UL, and cUL, meeting the industrial equipment access requirements of most regions around the world and adapting to the global production layout of multinational enterprises.
