What is the Dupline bus system?

Dupline is Carlo Gavazzi's simple two-wire fieldbus for distributed I/O in building automation and industrial applications. It allows sensors, switches, and actuators to be connected over distances up to 10km using standard cable, reducing wiring costs compared to traditional point-to-point connections.

What is the Dupline Parking Guidance System?

Carlo Gavazzi's Parking Guidance System (PGS) uses Dupline technology with ultrasonic sensors to detect vehicle presence in parking spaces. Multi-color LED indicators show space availability (green=free, red=occupied), and the system provides real-time occupancy data for wayfinding displays and management software.

How many devices can connect to a Dupline network?

A single Dupline channel supports up to 128 addresses with thousands of I/O points possible through grouped addressing. Multiple channels can be used for larger installations. The system uses time-division multiplexing for reliable communication without complex addressing or programming.

Product Brochure Dupline® - the versatile bus for Industrial Applications and Building Automation. Dupline is used for transfering Analog and digital information over distances up to 10 km. It can be used stand-alone or as part of a PLC based control system. There are no special protocols to learn - all modules are simply and quickly configured with a small hand-held device.

Dupline is used extensively in mining (ventilation, lighting, and conveyor control), elevators (for signal transmission), irrigation systems, water treatment facilities (signal monitoring, control), facility alarm systems, and in building automation (temperature and lighting control, security).
