About the product 

iSMA-B-2D1B has been built in order to control light and a blind/shutter motor 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 a common light switch and a common presence detector without the need of programming, which makes iSMA-B-2D1B the unique plug& play type device dedicated to DALI network control. In addition iSMA-B-2D1B has blind/shutter control function implemented, which allows to control a blind/shutter motor by a common double-switch. The controller is factory-equipped with the RS485 interface which is the physical layer for the most popular open communication protocol Modbus ASCII/RTU.

Key Features

  • Addressing from 0 to 255 by DIP-switch
  • 230 V AC power supply

Good durability
Style: 10-in-1【1 HDMI+1 VGA】
I had the 8 in 1, but realized I needed one more usb hub for my current setup when using dual screens, scanner, printer, and drives, this seems to do well, is a bit heavier than the previous model as expected. Good material and easy to unmount quickly from the computer. Works with usb c connections so perfect for my Surface Pro 9.
