I'm going to setup a test system for switching 30x24V from a RPI and your stackable relay hats look really suitable for this. What I wonder is how I best distribute the power? I'm thinking of having a 230VAC to 24VDC supply and then split this into 30 wires that I connect to the relay terminals. Is there any standard module that I can use to help me split up the power like that? Or what's the common approach here? Maybe something DIN rail compatible.
