iSMA-B-2D/2D1B
To simplify the commissioning process, the controllers come with a built-in application that supports the most popular lighting control applications in one room of the building.
The device is used to control two separate DALI light areas with up to 32 DALI ballasts. It offers a light level control mode that maintains the set light level in up to two separate zones. The built-in two special inputs and four digital inputs are used to connect presence sensors, light switches and light level sensors. A dedicated CFG DIP switch allows you to activate a predefined input configuration.
Out of the box, the device enables the control of DALI prefixes with a light switch and presence sensor, or in LLC mode, without programming, which makes the iSMA-B-2D a unique plug&play device for DALI network control. The controller is factory-equipped with an RS485 interface, which supports the most popular open communication protocol, Modbus ASCII/RTU. Up to 128 devices can be connected to this bus.
The device is also available with Wieland connectors: 2D-WD and 2D1B-WD
