Solid state relays with DIN rail mount

DIN Rail mount is one of the main mounting style used in industrial installations. A DIN rail is metallic and its dimensions have been standardised by the Deutsches Institut für Normung (DIN), the German institution of normalisation that created this standard. A DIN rail usually is 35 mm wide and is generally installed in electrical cabinets to fix small electrical equipments, such as solid state relays.
