BOM

BOM

The BOM only lists components that are necessary to manufacture the individual assemblies. Cables, plugs, DIN rails, wiring channels, [material for mounting the modules in the housing]{.underline}, etc. must be put together individually depending on your housing. In the column Source is listed where we got the parts; these sources are not an advertisement or recommendation for certain sellers or platforms, but are merely intended to indicate where the material could be sourced.
