Integrating Modbus RTU/ASCII networks with modular I/O systems, the Beckhoff BK7350 bus coupler serves as a reliable interface between the Modbus fieldbus and Beckhoff Bus Terminals. This compact module manages communication for up to 64 Bus Terminals, with expansion capabilities reaching up to 255 terminals using a K-bus extension. The BK7350 automatically configures and maps the connected digital and analog peripheral signals to the Modbus process image, ensuring seamless data exchange in decentralized automation architectures.
The unit features a standard RS485 physical interface via a 9-pin D-sub connector, supporting data transfer rates from 150 baud up to 38,400 baud. Configuration can be executed directly using the integrated rotary address switches or via the KS2000 software tool. Designed for harsh industrial environments, the module features robust electrical isolation between the power contacts, supply voltage, and the fieldbus network.
