Key benefits Provides clean, optically isolated signal conversion between NPN and PNP systems, preventing interference, ground loops, and false triggers. Enables direct control of signal on/off or small loads through built-in double-conductive electronic switching, simplifying wiring and reducing the need for extra components. Supports bidirectional conversion: convert PNP to NPN or NPN to PNP across eight channels, making it a flexible interface for mixed-signal installations. Main features Standard input voltage: 10–28 V. 8-channel level converter for multi-signal installations. Optically insulated digital channels for stable, interference-free signal transmission. Double-conductive electronic switch outputs allow the terminal block to act as a reliable on/off controller for signals or small loads. 100% new, high-quality product with long service life and consistent performance. Function and compatibility Converts and isolates sensor and control signals between PNP and NPN devices, ensuring compatibility between different equipment types (sensors, PLC inputs, controllers). Works with standard 10–28 V industrial signal levels commonly used in automation and detection systems. Designed for straightforward integration into terminal-block wiring systems and control cabinets. Practical advantages Improves system reliability by isolating sensitive input points from electrical noise and transient events. Reduces component count by combining level conversion, isolation, and switching in a single terminal block. Facilitates maintenance and diagnostics by providing a clear, modular interface for multiple channels. Typical applications Factory automation: Interface PNP sensors to NPN PLC inputs (or vice versa) while isolating noisy field wiring. Detection and monitoring devices: Use the terminal block’s electronic switch outputs to control indicators, relays, or other small loads in inspection and alarm circuits. Control panels and retrofit projects: Simplify wiring when integrating equipment with differing transistor output types or when adding isolated signal inputs to existing racks. Performance and build Optically isolated channels deliver high signal integrity and reliable switching behavior. Designed for durable operation and consistent long-term performance in industrial environments. Compact 8-channel form factor supports organized installation in control panels and terminal strips.
