4086050461 Homag Bk3120 Beckhoff Ethercat Bus Coupling Coupler

1、Precise matching of industrial signal acquisition function configuration

 The Beckhoff BK3120 features an 8-channel digital input design, with each channel supporting the standard 24V DC industrial voltage and a maximum input current of 5mA. It can be directly connected to common industrial sensors such as photoelectric switches, proximity switches, and limit switches without the need for additional signal conversion equipment, enabling accurate collection of the on-off status signals of on-site equipment and meeting the basic digital input requirements of small and medium-sized control systems.

2、High compatibility with the K-bus bus system

As one of the core models in the Beckhoff K-bus terminal module series, the BK3120 can seamlessly work with K-bus couplers (e.g., BK9000) to quickly integrate into the Beckhoff distributed I/O architecture. Its communication protocol is fully compatible with the K-bus standard, enabling real-time data interaction with Beckhoff PLCs, industrial PCs (IPCs), and other controllers without complex protocol debugging, significantly reducing system integration difficulty and improving project deployment efficiency.

3、Design of multiple electrical isolation for system security

To cope with complex electrical interference in industrial environments, the BK3120 is equipped with 500V multiple electrical isolation protection, covering three key links: "power contact - power supply voltage - fieldbus". This design can effectively block the impact of interference signals such as ground loops, voltage spikes, and electromagnetic coupling on the internal circuit of the module and the backend control system, avoiding signal distortion or equipment damage caused by electrical interference, and significantly improving the operational stability and safety of the entire control system.

4、Industrial standard installation and protection specifications

 In terms of installation adaptability, the BK3120 strictly complies with the EN 60715 standard, allowing direct installation on 35mm DIN rails, and supports side-by-side installation via double-slot key connections. This makes full use of the vertical space in industrial control cabinets and simplifies the installation process when multiple modules are densely arranged. In terms of protection performance, the module's enclosure has an IP20 protection rating, which can effectively block dust intrusion and prevent accidental contact with internal circuits by personnel, meeting the basic protection requirements in industrial control cabinets.

5、Wide temperature and anti-interference capability to adapt to harsh environments

The BK3120 has excellent environmental adaptability, with an operating temperature range from -25℃ to +60℃. It can maintain stable operation even in scenarios with large temperature fluctuations, such as outdoor low-temperature equipment cabinets and high-temperature production workshops, without the need for additional temperature control equipment. At the same time, the module's electromagnetic compatibility (EMC) complies with the EN 61000-6-2 (electromagnetic interference immunity) and EN 61000-6-4 (electromagnetic emission immunity) standards, ensuring the accuracy and reliability of digital signal collection even when used near strong electromagnetic interference sources such as motors and frequency converters.

1、Industrial automation production line field:

It can be integrated into automation production lines such as auto parts manufacturing, electronic component assembly and mechanical processing. It is used to collect digital signals output by detection components such as photoelectric sensors, proximity switches and travel switches, so as to realize real-time monitoring of the operation status of production equipment, workpiece positioning and process flow, and ensure the continuous and stable operation of the production line.

2、Smart manufacturing and smart factory scenarios:

In the smart factory architecture based on the Industrial Internet of Things (IIoT), this module can work in coordination with Beckhoff PLCs, bus couplers and other equipment. It transmits digital data such as the switch status of on-site equipment and fault signals to the upper-level control system or monitoring platform, helping factories realize equipment status visualization, digital management of the production process and intelligent decision-making.

3、Process control-related fields

It is suitable for process control scenarios such as chemical industry, food and beverage, and water treatment. It can collect digital information such as valve switch status, pump operation signals and liquid level switch signals. Cooperating with the control system, it realizes real-time monitoring of the start-stop control and working conditions of key equipment in the production process, and meets the demand for real-time feedback of equipment status in the process industry to ensure the stability of production process parameters.

4、Logistics and warehouse automation systems: In the control systems of equipment such as stackers, conveyors and AGVs (Automated Guided Vehicles) in smart warehouses, it can be used to collect signals such as position detection switches, emergency stop buttons and safety door switches. It realizes accurate monitoring of the operation trajectory of logistics equipment, action execution and safety status, and ensures the efficient and safe operation of the warehouse logistics system.

5、Support for small and medium-sized automation equipment

It is suitable for small and medium-sized automation equipment such as packaging machinery, printing machinery and textile machinery. As a local digital signal collection unit of the equipment, its compact size (51mm×100mm×69mm) facilitates flexible installation in the equipment control cabinet. At the same time, the IP20 protection level and wide temperature operating range can adapt to the installation environment of the equipment site and meet the reliability requirements of the equipment for signal collection.
