iSMA-B-2D Light ControlleriSMA-B-2D device has been built in order to control light in a single space in the building.
The iSMA-B-2D device 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. It offers a light level control mode, which maintains set light level in up to two separate zones. Built-in two special inputs and four digital inputs are dedicated to connect presence detectors, light switches, and light level sensors. Dedicated CFG DIP switch allows to activate a predefined inputs configuration. Out of the box, the device allows to control DALI ballasts by light switch and presence detector, or in the LLC mode, without the need of programming, which makes iSMA-B-2D a unique plug&play type device, dedicated to the DALI network control. The controller is factory-equipped with the RS485 interface, which is a physical layer for the most popular open communication protocol Modbus ASCII/RTU.
