Wiring two time switches together

[Mabalingwe]

Hello,
I want to wire a time switch to run a small electric motor.
I need this to be programmable to run several times per day.
It only needs to run for less than a minute but this needs to be programmable to alter the number of seconds it runs for each time.

Is there a single product which will achieve this or will I need to wire two time switches together, the first to start the motor at the appointed times and the second to run for the programmed number of seconds?

I hope this makes sense and I appreciate any assistance anyone can offer

A PLC will clearly do this where I worked rule of thumb was any machine needing 5 timers or more convert to PLC control.

There are other programmable units which are easier to program and using a PIC is far cheaper but harder to program and the Arduino is half way between the two easier than a PIC but harder than a PLC to program.

To me the big stumbling block is price of programming cables and software. Been out of it for 10 years now but there were some cheap options where the PLC cost a little more but the lead was cheap and software was free.

Thank you for your help.
I wasn't very clear with my original post, in that the motor I want to run is only a small 15w one.
one idea I saw was using a DC 12V LED Display Digital Delay Timer Control Switch Module to set the times of day and a AC 110V Digital LCD Power Programmable Timer Time Switch to set the length of time to run the motor for.
This will work, but as I have no experience of wiring I'm looking for help as to how to do this.
Of course, if there is a single unit which will do this that would be great. The PLC route would be ok, but is more expensive than I want.
Please ask for clarification if you need it

I agree with Eric

But depending on exactly what is needed and how variable the start times and run times are and how they are to be set by the user it may be possible using a few "off the shelf" timers and time delay relays.

Eric. I still use the MicroChip MPLAB ICD 3 and MPasm ( assembly language ) for specials and the control systems for the cottage.

Would a heating controller do it - ours has several on-offs but is limited to whole minutes. Probably gives 240v out but there may be some that are volt free.

Thanks IJWS15,
Thereby is the route of my problem
The DC 12V LED Display Digital Delay Timer Control Switch Module can only be set to run for a minimum of one minute, which is too long.
That is why I'm thinking that the 110V Digital LCD Power Programmable Timer Time Switch is wired to the Digital delay timer, when that starts the motor running the programmable timer time switch, which can be set to anything from one second upwards runs the motor for the pre-set number of seconds and then stops.
As these two timers can be obtained for just a few pounds and I have seen it in operation, it seems like a good idea
But, as I have no experience of wiring I'm looking for help as to how to do this.
