Carlo Gavazzi G50102206 – Dupline-Powered Dual-Channel Digital Input Module
The Carlo Gavazzi G50102206 is a high-performance dual-channel digital input module designed for the Dupline® fieldbus system – Carlo Gavazzi's proprietary two-wire fieldbus technology engineered for long-distance, high-interference, and cost-effective industrial sensing and control applications. This module serves as a reliable input node that acquires field switch signals and converts them into Dupline bus signals for stable, long-distance transmission.
Key Features
Dual-Channel Digital Input – The module features two independent digital input channels, supporting dry contact, PNP, and NPN signal inputs. It quickly responds to input state changes, ensuring accurate and stable data acquisition.
Dupline Bus-Powered – The G50102206 is powered directly by the Dupline two-wire bus, eliminating the need for an external power supply. This significantly reduces wiring complexity and installation costs.
Ultra-Long Distance Transmission – Leveraging Dupline's low-frequency carrier technology, the module supports communication distances of up to 10 kilometers per bus segment, far exceeding traditional fieldbus systems like RS-485 (1.2 km).
Mini-E Housing with Flexible Mounting – The compact Mini-E housing supports both direct wall mounting and 35mm DIN rail mounting (via DIN-rail adapter), enabling rapid deployment in various industrial environments.
Built-in Pulse Prolongation – An integrated pulse prolongation function prevents signal loss caused by mechanical contact bouncing or short pulses, improving PLC acquisition success rates.
Superior Noise Immunity – The Dupline system employs low-frequency (<9.6 kHz) current-driven communication, offering exceptional resistance to electromagnetic interference (EMI) from variable frequency drives, motors, and high-voltage cables.
IP20 Protection Rating – Rated IP20, the module is suitable for installation in control cabinets and industrial control environments.
Wide Operating Temperature Range – The module operates reliably in temperatures ranging from -20°C to +50°C, making it suitable for demanding industrial conditions.
