Thank you for the Links.
-. I did not mean the very exact board in the pictures, but something like that (a board with all the components). Wanted a board to use directly. The links you sent me are what I meant when I asked for, if you know of a relay board that would work/do the same. Thank you.
-. For both boards you've linked: (1) the SSR (Solid State Relay) (2) the Fiber Glass Relay, what would the circuit diagram look like? (the Wiring).
If you look at the actual devices I linked it should be easy to figure out how to connect them. But here goes. For the relay board there are six connections and they are marked on the right side NO, NC, C, and -NEG. On the left side they are marked NO, NC, C, and +POS. ON all relays NO means Normally Open. NC means Normally Closed. C means Common. These three connections are all in regards to the contacts or switched section of the relay. The NEG and POS refer to the coil which in this is polarized and the connection polarity is critical. Not all relay coils are polarized but this one is. So looking at my diagram again and putting this board in place of the relay your connections would be as follows.
Control signal from controller to POS+
Ground or negative from controller to NEG-
All fans and motors + to the NO on only one side of the board.
Positive from 12 volt supply to C on the same side of the board that fans and motors are connected to.
You will ignore the C, NC, NO connections on one side of the board.
For the Solid State relay, the connections are numbered and the control side is marked input while the switched side is marked output. So I will use numbers here as well and this is the case on most SSR's. I will go ahead and give you the correct connections BUT I just noticed this relay is rated at a 3 amp load and that is not going to be enough so we will need to source one that can handle 5 amps.
SSR1 will be the Positive from your 12 volt supply.
SSR2 will be the positive from all fans and motors.
SSR3 will be the output from your controller.
SSR4 will be the ground from your controller.
I am not able to source a Solid State Relay at this time with the correct current rating, so just go with the relay board. It will work just as well.
