Function and Positioning

The 0TB2105.9110 serves as a standard wiring interface for B&R X20/X67 series I/O modules, PLCs and automation PCs. It provides secure, maintenance‑free electrical connections for digital inputs/outputs, analog sensors and actuators, and 24 VDC power distribution. The dual‑function push‑in/cage‑clamp system allows both tool‑free fast insertion and tool‑assisted high‑torque termination, adapting to different on‑site wiring habits. It effectively prevents loosening caused by vibration or thermal cycling, ensuring long‑term signal integrity and system stability. Positioned as a versatile, high‑reliability connection solution, it is suitable for both standard and demanding industrial applications.
