In model maker make a simple model by:

  1. add a raster later variable and provide image name to be split
  2. place a function object and link with raster input just provided as above.
  3. double click on function object & now you will see a raster variable listed in top left corner & 3 more names (assuming 3 bands in raster) with suffix (band number)
  4. Select the band you wand to separate.
  5. Place a raster object and connect the function to this raster object.
  6. Double click on raster & provide a name as well as data type for the raster output.
  7. Run the model & you have a raster image with band you required
