The TURCK B8141-0 is a high-density, dual-level passive interface module developed for professional signal management in modern control systems. It features 12 dual-level terminal channels, allowing two separate signals to be routed per terminal row—significantly optimizing space utilization in tight control cabinets. Each signal channel is equipped with its own LED indicator to provide clear, instant diagnostics for input/output status. This makes it easier to verify wiring and identify malfunctions during installation, commissioning, or maintenance, minimizing system downtime. The robust screw-type terminals ensure strong, reliable, and vibration-resistant connections. Designed for DIN rail mounting, the B8141-0 is an ideal solution for high-channel-count signal distribution in PLC systems, machine automation, and distributed control architectures. Key Features: • Dual-level terminal interface module – supports compact signal wiring • 12 channels with LED indicators for real-time diagnostics • Efficient use of panel space – ideal for high-density control cabinets • Passive operation – no external power for signal routing • Screw-type terminals – ensure secure and long-lasting connections • DIN rail mountable – quick and easy integration • LED feedback reduces troubleshooting time • Perfect for PLC I/O systems, sensor/actuator wiring, and OEM control panels
