iSMA-B-2D

DALI lighting configurable controller with Modbus RTU communication.

Experience our Light Controller
To minimize time and simplify the commissioning process, the 2D 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 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 controller is ready for operation out of the box, you just have to configure the controller using built-in DIP switches.
