The SBWEB saves up to 80% of wiring and installation costs by eliminating multi-conductor "home run" cables from field devices back to DDC controllers. The SBWEB collects the signals from analog and digital field devices and sends them over long distances via a simple, inexpensive pair of wires. Since the SBWEB also increases the possible distance between field devices and DDC controllers, cost will be reduced by decreasing the number of necessary controllers.

With the Dupline® bus-powered sensors and small decentralized I/O-modules installed at the actual sensor/actuator location, the field level wiring is greatly reduced. The operating range and I/O capacity of the DDC is increased, which means that a given installation can be realized with a reduced number of DDCs. The de-central I/O concept also provides a high flexibility for system enhancements and last minute changes.

Above you’ll see how the new line of bus-powered CO₂, temperature and humidity sensors can provide significant wiring advantages in HVAC control systems, especially in those cases where the sensors are widely distributed into several rooms of the building. The Dupline® 2-wire bus cable is simply multi-dropped from sensor to sensor collecting all the measured values – no power supply is required. If additional sensors are needed later on, it is merely a question of connecting them to the already existing bus cable. The measured values can be shown on the optional backlit LCD display.
