We could use some more info on the project.
Am I right in assuming that the contraption has a built-in motor that is supposed to run for the specified time, then stop?
What are the parameters of the motor (supply voltage, current)? Probably either of the modules is suitable.
This is how one of the modules is to be wired:

12 V power supply for the module in red, relay contact (switch) in blue. Note that the relay contact is separate from the 12 V supply. Therefore you can use it to switch any voltage as required for the motor, as long as the voltage and current are within the limits of the module.

In the above example a separate 24 V power supply is being used for the motor. This is only an example. Any other power source as required for the motor will do. Of course you can also use the same 12 V for the module and the motor, if convenient:

Notice the black component in the top left corner with the label "remove seal after washing"? This is a buzzer. One German reviewer noted that this buzzer is rather loud and annoying. He removed it from the board.

Hope this helps,

Harald

WOW technical :eek::eek::eek:

Due to MY Autism and being 60+ I am my sons carer, due to HIS Autism he will never have a full time job so he decided to (with me) design a film processor

NEITHER of us had ANY idea of materials, where to get them, what to use, after a YEAR we now have this (it now has a two way backward and forward switch added ;) not in this image

I knew NOTHING about gears, what a PILLOW bearing was, and as for variable speed switches on the left :(

THIS wads one of the first he designed

Hello,

For the board in post #5 the pins have the following functions:
GND , Negetive from power supply.
VCC , positive from power supply.
COM , common contact of output relays.
CB , Circuit break contact of relays.
CK , Circuit make contact of relays.

IN , could be a trigger signal (not sure).

Bertus

Vcc is a name given to the positive supply voltage in many circuits. The origin is in bipolar digital integrated circuits where the positive supply voltage was often connected to the common collector side of the NPN transistors in the circuit, hence the "cc". If you're interested, you may read more detail here. But in essence it is only a name, one could call this Vp ("p" for positive), Vs ("s" for supply) or any other name.
