There are 2 types of hardware available:
The -WD part in the device name indicates that instead of the screw terminals, the Wieland type connectors are used for 230 V AC power supply, light output, and blind output.
The iSMA-B-2D1B-(WD) is equipped with a 230 V AC power supply and 2x 230 V AC normal closed light outputs for the lamps for power supply if the lighting is controlled with the DALI network, and one double blind output dedicated to blind/shutter control. All these outputs are fuse protected and connected to the controller’s main power supply as presented in the figure below.
In addition, the light outputs work as relays in the ON/OFF light control mode.
The controller is equipped with a 24 V DC power supply dedicated for power supply of motion sensors\presence detectors, which need an external power supply.
The input section consists of 2 special inputs dedicated for motion sensors / presence detectors connection and 4 digital inputs for connecting the switches.
WARNING! The maximum current for all the outputs is 8 A!
