The TURCK B8151-0 is a space-optimized dual-level passive interface module engineered for efficient signal and power management in industrial automation environments. This model not only offers 12 high-density terminal channels but also integrates power distribution lines alongside signal routing. Each channel includes built-in LED indicators that visually communicate signal status, simplifying diagnostics and improving operational reliability. Designed for DIN rail mounting, the B8151-0 supports both signal and auxiliary voltage lines in a compact footprint. The dual-level terminal layout allows separate routing of I/O signals and common power potentials, enabling structured and clean panel wiring. Screw-type terminals provide secure and vibration-resistant electrical connections, suitable for high-demand applications in machinery and process control. The combination of signal transmission, LED feedback, and integrated power routing makes this module an ideal choice for control panel builders aiming to reduce wiring complexity while maintaining serviceability. Key Features: • Dual-level terminal layout – for signal and power line separation • 12 channels with integrated LED indicators for diagnostics • Enables structured wiring of both signals and auxiliary voltage lines • Compact DIN-rail housing for dense cabinet integration • Screw-type terminals – secure, reliable under vibration • Reduces panel space requirements and troubleshooting time • Ideal for decentralized I/O, PLC cabinets, and automation panels • Designed for easy identification, testing, and maintenance
