Decentralised interface for building automation

Carlo Gavazzi, building automation, controls, BEMS

Carlo Gavazzi has extended its Dupline range of bus offerings for building automation with the introduction of decentralised analogue-input modules. These new modules enable control systems to interface in a decentralised manner with environmental sensors in smart building systems. They can be used with any type of environmental sensor with a 0 to 10 V or 10K3 output.

The addressable device is typically installed behind the environmental sensor and wired by looping the 2-wire bus cable from sensor to sensor. Many sensors can be networked back to a Dupline gateway device, where all the sensor information is available to the BMS via a Modbus serial or TCP connection. This approach is considerably simpler than traditional parallel wiring. Initially, three modules are available with up to four analogue inputs, each with 8-bit resolution.
