HowTo: Compact 4 Port SSR Box
( Frank Kostyun)
Step 1 : Creating the Circuit Board
|
| | You will first need to create a circuit board to control the four ports. There are links to the image files for the board.
The RJ45 jack is drilled with a #70 wire size drill bit, the relay drill is a 7/64, and the holes for the #12 wire are a 1/8 drill bit.

It would also be easy to use your own SSR's on this.
