The controller would be connected to an air valve box or boxes. Inside each air valve box there are four air solenoids so each air valve box and handle four sections. Each air valve box has an Air IN port and four Air OUT ports. Each Air OUT port can handle one or more of your Trimble air clutches.
When I had a Deere 12 row 1760, I set it up with 4-3 row sections. This meant that each Air OUT port line was split three ways to handle 3 row clutches. The output from the air compressor tees into an air tank for a reserve supply, the line then leads to the Air IN port of each air box. This means the Air IN line may need to be split if more than one air valve box is used.
On larger planters, it is common to use two air tanks so the system has plenty of reserve capacity to activate all rows when approaching a "square" headland.
