Sure, just searching for 'DIN rail terminal block' should turn up lots of options. I like this spring contact style, they allow ferrule-terminated wires to be pushed directly into the terminal and have a small pushbutton to release, which makes them very easy to use:
https://www.altechcorp.com/CP/ There are plenty of other options, though, from major manufacturers as well as cheap clones, so take your pick. Generally you stack as many terminals as you need next to each other, and then insert jumper strips to electrically connect adjacent terminals as needed.
For power distribution, double level terminals that allow both levels to be jumpered independently work very well. You can use one level for positive and the other for negative, and land the each pair of fan wires at the top and bottom positions on a single terminal. I used them to wire up 24VAC zone valves for my heating system, photo attached. You can see that there is a continuous jumper (orange strip) on the lower level to join all of the neutral/common connections together, and three separate jumpers on the top level to join the live connections into three separate zone groups. Single-level blocks would require each load to connect to two different groups of terminals, so this keeps the wiring much tidier.
