SSRez

==Introduction==
There are lots of SSR designs out there. However, John's SSRoz is one of the best. It is compact and functions great and without this initial work, the SSRez may not exist! However, a shortcoming of the design was that it was not designed with a specific enclosure in mind. The initial move towards the SSRez involved changing the layout to fit the TA-200 Telephone Demarc Enclosure. At Chris Foley's request John redesigned the layout of the PCB and the SSRez was born.

In order to keep the board to a minimum size and the board cost down, the SSRoz has all the neutral connections off board. So, take all the neutrals and connect them with a large wire nut (five 16AWG neutrals!) Once connected, where does the massive chuck of wire go? :) This led to adding terminals for the neutrals...now this is not inexpensive. The cost was offset in part by removing the vertical fuse holder and replacing it with inexpensive fuse clips.

Lastly, the RJ45 connector could be difficult to remove with the locking pin as the pin ends up in a tight corner. A vertical RJ45 jack made this so much easier. Now, some users like the right angle connection. The great thing is that both types will fit the board. So, if you want the "Dino Option" feel free to use the right angled connector.

While changing every thing around, the power traces were beefed up a bit to allow a slightly higher power throughput. This allows for a 7A fuse in place of the original SSRoz fuse of 5A.

so....start out trying to change one problem..and end up with a whole new layout!

The SSRez can be used as is for most all of the designs found on DIYC, and specifically the [[REN64]].
