iSMA-B-2D-WD

Experience our Light Controller
To minimize time and simplify the commissioning process, the 2D-WD controller is delivered with a built-in application, which supports the most popular light control applications in a single space in a building. The controller is dedicated to controlling two separate DALI light areas with up to 32 DALI ballasts.

2 Special Inputs
Built-in two special inputs are designed to control the light via connected motion sensors or presence detectors. Additionally, special inputs may read the light level intensity from standardized sensors.

4 Digital Inputs and Outputs

The controller is equipped with four dry contact inputs onboard:
2 digital inputs for control of the light by connected monostable or bistable switches
2 digital inputs for occupancy sensors
2 light outputs
The device is equipped with two fuse protected light outputs 230 V AC, with a maximum 4 A load. The outputs can work in two modes defined via DIP switches: DALI or ON/OFF.

24 V DC Power Supply Output
The device is equipped with a 24 V DC output for providing power for motion sensors or presence detectors, which demand an additional supply.

Open Communication
The 2D-WD controller is equipped with RS485 interfaces with open protocol Modbus RTU/ASCII. You can connect up to 128 devices on one bus.

Simplified Configuration and Commissioning Process
The 2D-WD controller is ready for operation out of the box, you just have to configure the controller using built-in DIP switches.
