BX5200 Beckhoff Fieldbus Modules & Gateways

The Beckhoff BX5200 controller is a core component of the BX Bus Terminal Controllers series, designed to manage distributed I/O in demanding industrial automation environments. Featuring 64 bus terminals as standard—expandable to 255 via K-bus extension—and automatic data transfer rates of up to 500 kbaud , it delivers high-speed communication for process control. An integrated FSTN display with 2 x 16 illuminated characters provides clear, real-time status updates and parameter feedback, making it ideal for machine builders and system integrators requiring compact yet powerful bus terminal control. Delving into its technical specifications, the BX5200 supports a comprehensive I/O set with 2,040 digital inputs/outputs and 512 analog inputs/outputs to interface with sensors and actuators. The fieldbus interface accommodates up to 512 bytes of input and 512 bytes of output per cycle, while the process image extends to 2,048 bytes in and out , ensuring ample data throughput. A flexible serial interface offers COM1 (RS232) and COM2 (RS232 or RS485) ports, alongside an open-style 5-pin connector for K-bus wiring. Integration across network topologies is enhanced by the CANopen-based subsidiary bus system (SSB) . Diagnostic capability is further strengthened by LEDs indicating power supply status and K-bus activity, and a joystick switch enables intuitive on-device parameterization and troubleshooting. The BX5200 operates on a 24 V DC (-15%/+20%) supply, drawing 140 mA plus one quarter of total K-bus current (max. 500 mA) , and incorporates a battery-powered real-time clock for accurate time and date stamping of process events. Its illuminated FSTN display and robust LED diagnostics ensure visibility and quick fault identification even in low-light conditions, enhancing operational efficiency. With compatibility across a range of fieldbus and network standards, this controller delivers reliable performance, simplified maintenance, and scalable architecture—key benefits for large-scale, time-critical industrial automation applications.
