A while ago I was working on a prototype project for a company I was the cofounder of and later sold. The needs of this project called for the use of Solid State Relays for automation projects. We decided to work with Solid State Relays out of the safety factor of having the high voltage and low voltage circuits separated. Blow are some of the pictures of the very early prototyps of projects that these boards were used in.
Under a new startup company we are currently working on some new ideas of small sized relay boards for home automation projects. If you are interested in getting your hands on one of these boards im sure I can find a few extras laying around, so feel free to just send me an email.
Here is the datasheet for these prototype boards: SRB1-RevB
