The TURCK B8241-0 is a professional-grade passive interface module developed for structured and efficient signal distribution in control cabinets. It offers 12 signal channels, each paired with LED status indication and a shared common ground line, enabling simplified wiring schemes for sensors and actuators. This module is particularly effective in systems where multiple input or output devices share a common reference potential. By integrating LED indicators, technicians and engineers can instantly verify signal activity, reducing the time required for commissioning and fault isolation. Its screw-type terminals ensure strong, reliable connections, while the DIN rail-mountable housing allows for space-efficient installation. Ideal for use in PLC control systems, remote I/O distribution boxes, and machine automation where signal organization and visibility are key. Key Features: • 12 signal channels with built-in LED indicators • Shared common ground line for efficient wiring • Suitable for connecting multiple I/O devices with shared reference • Passive signal routing – no active electronics required • Screw terminals for vibration-proof electrical connections • Space-saving DIN rail mountable housing • Enhances visual diagnostics during commissioning and maintenance • Widely used in machine control systems and modular I/O cabinets
