Product Description:

The Beckhoff BK3000 is a compact and efficient EtherCAT bus coupler. It is designed for connecting decentralized I/O terminals to a fieldbus system. The BK3000 accommodates up to 64 bus terminals, making it suitable for medium-sized automation or industrial setups. It operates on a 24 V DC supply voltage and has an input current of 70 mA, with a maximum of 500 mA. The module can manage 256 digital and 128 analog peripheral signals, ensuring smooth data exchange and control in industrial environments.

The module supports a baud rate of 1.5 M baud, which plays a critical role in improving communication speed. This high-speed data rate ensures fast and reliable communication between the coupler and connected devices, lowering response time and improving overall system responsiveness. It supports DP and FMS protocols, which are common in industrial communication networks, ensuring compatibility with a wide range of automation systems. The coupler communicates through a D-sub-9-pin bus connection, which provides a stable and secure physical interface for data transmission, thus widely used for PROFIBUS networks due to its durability and ease of use.

The BK3000 EtherCAT bus coupler also features 24 V DC/AC power contacts, which allow it to power connected I/O terminals reliably. This makes the coupler suitable for both direct current and alternating current systems. It operates within a temperature range of 0 degrees C to +55 degrees C. It has a protection class of IP20, and the BK3000 is suitable for installation in control cabinets. Due to its robust features and support for fast and flexible communication, the Beckhoff BK3000 is an excellent choice for industries requiring scalable and efficient I/O solutions.
