Carlo Gavazzi’s SB2REP230 repeater can increase transmission distance by up to fourfold when used in systems with high loads in a typical building-automation application. This capability increases the opportunity to install many more bus-powered devices on the Smart Dupline bus. It also makes network design far simpler as this repeater can be connected to any point on the Dupline bus.

This repeater can be powered by 115 or 240 V AC and also acts as an isolator. It regenerates the voltage levels of the Dupline carrier signal and provides an output load capability of 300 mA, complete with isolation between the primary and secondary sides. A short circuit on the secondary side will not affect the primary side, and the system will restart automatically within 10 s of the short circuit being removed.

The Smart Dupline bus wiring topology is completely free using an unscreened 2-core bus cable. A 4-core cable can be used to carry power for devices such as sensors.
