Carlo Gavazzi Dupline Fieldbus Gateway SD2DUG24 is a high-performance industrial communication gateway designed to connect Dupline® fieldbus networks with Modbus RTU control systems. Acting as a Dupline channel generator, synchronization unit, and RS485 Modbus interface, the SD2DUG24 enables reliable data exchange between field devices and PLC, DCS, SCADA, and Building Management Systems (BMS). It supports both 2-wire and 3-wire Dupline installations, providing a flexible and scalable solution for industrial automation and smart building applications. The gateway is fully programmable via dedicated configuration software, allowing users to customize communication parameters and channel assignments according to specific project requirements.

Designed for DIN-rail installation, the SD2DUG24 features a compact 2-DIN housing, making it suitable for control cabinets where installation space is limited. The device supports up to 128 Dupline channels and is compatible with all Dupline communication protocols, enabling seamless integration with existing Dupline systems. LED indicators provide real-time status monitoring for power supply, Dupline communication, and RS485 network operation, simplifying installation, commissioning, and maintenance. Its high immunity to electrical noise ensures stable communication even in demanding industrial environments.

The SD2DUG24 significantly reduces wiring complexity by utilizing the Dupline two-wire fieldbus architecture, which supports long communication distances without requiring specialized cables. This helps minimize installation costs while improving system flexibility and scalability. Engineers can easily expand automation systems by adding additional Dupline modules without extensive rewiring, making the gateway an ideal choice for both new installations and modernization projects. The integrated Modbus RTU interface allows straightforward communication with industrial controllers, enabling efficient monitoring and control of distributed I/O devices.

Typical applications include industrial automation, factory process control, HVAC systems, energy management, water and wastewater treatment, transportation infrastructure, and intelligent building automation. Whether integrating sensors, switches, relays, or remote I/O modules, the Carlo Gavazzi SD2DUG24 provides reliable and efficient communication between field devices and higher-level control systems.
