B-2D-WD
iSMA
iSMA-B-2D-WD has been built in order to control light in a single space in the building. The device is dedicated to control two separate DALI light areas with up to 32 DALI ballasts. Built-in two Special Inputs and two Digital Inputs are dedicated to connect presence detectors and light switches.
Dedicated DIP-switch allows to activate predefined inputs configuration. Out of box the device allows to control the DALI ballasts by acommon light switch and a common presence detector without the need of programming, which makes iSMA-B-2D-WD the unique plug& play type device dedicated to DALI network control. The controller is factory-equipped with the RS485 interface which is the physical layer for the most popular open communication protocol Modbus ASCII/RTU.
