A Better Relay board


This is a much nicer relays board than my last one which was more for experimentation more than anything just to see if certain things were going to work the way I wanted them too. This new one I put together is better laid out, has more relays on the board and more terminals for the DTMF request from the Voice Box. The board is a little shorter than my old one width wise but a little higher height wise but given that it better made and has more on it I'll be able to work that under the passenger side of the dash a lot easier than my last set up. This new board also has Rectifier Diode Bridges built in before each relay so this will eliminate the problem I was having with switches that activated relays interrupting my SFX module when the relays were switched off. I'm a little fuzzy on how that works exactly but it works and it cured the problem so that is what counts. ;)
