I'm using a 12vdc power supply to drive 2 octal base relays. Is there any reason I couldn't use a simple voltage divider to pick off 6 volts to control two solid state relays, as long as I didn't exceed the power output of the dc supply and have enough current flow to switch the ss realys. Also does anyone know the typical current draw for the control side of a 6-8vdc ss relay?
You could use a voltage divider but the load is also part of the equation. Not the way to go here. I would use a 6V regulator. As for the specs on the SS relays, you need to consult the data sheets or measure the current. Its really a fairly simple job once you figure what you need.

only that you don't appear to have the datasheet for the solid state relays, because if you did you wouldn't be asking this.

Your correct about the datasheet, I googled it off the net and even the though the ssr input terminals are labeled 3-8vdc, the datasheet has the more typical 3-32vdc. I connected it to 12vdc and the input current is as the datasheet states. No need to wicky up 6vdc off my 12vdc supply. This is a surplus ssr and must have been labeled for a specific use even though it works fine off 12vdc.
