B&R X20BR9300

Product Series: B&R X20 I/O System (X20BR Series)

Product Introduction: The X20BR9300 is a field wiring terminal block adapter for the B&R X20 I/O system. It provides a robust, screw-type or spring-clamp connection point for interfacing field cables to X20 I/O modules. It serves as the physical bridge between the control cabinet I/O modules and the field-side wiring harness.
