B&R X20BT9400 32-Channel Digital I/O Terminal – EtherCAT-Enabled Bus Coupler for Machine Control | T??V-Certified

Description

The B&R X20BT9400 is a TÜV-certified, EtherCAT-enabled bus coupler designed for machine control, part of the X20 series X2X Link I/O bus relay modules. As a 32-channel digital I/O terminal, it leverages EtherCAT technology, which delivers high real-time performance, flexible network topologies, and simple system configuration, making it suitable for demanding industrial automation applications. This device provides 5W of power supply support for connected X67 modules, ensuring stable operation of downstream I/O components. It integrates multiple protective features including reverse polarity protection, short-circuit protection, and overload protection, which enhance system stability and reduce equipment damage caused by abnormal electrical conditions. The X20BT9400 supports parallel connection for easy expansion of multiple devices, and offers redundant operation functionality: if a partial link or device fails, the system can maintain operation through redundant paths, significantly improving overall system availability and fault tolerance. Its X2X Link-based bus connection enables reliable integration of different bus devices to build robust industrial networks, ideal for use in automated production lines, packaging machinery, and other machine control scenarios requiring high reliability and scalability.
