Thanks to all who helped with advice on this system. Now when I press the start button on my thicknesser, buzzer, table-saw, my dust extractors start running and a pneumatic gate opens. When I turn the machine off, the extractor continues running for 30 seconds and the gate closes.
I used a very simple time-off delay using a capacitor, npn transistor and a relay.
The extractors are controlled with 80A SSRs
I have two relay boards to accept a closed circuit from each machine which holds a small power supply and relay. This to avoid any wires running in my workshop with high voltage.
If you are interested, I uploaded a video to youtube.
I am very happy this all came together. Once again thanks to all who gave me the advice I needed. Oh and the birds-nest inside my enclosure will be sorted lol. I also attached a picture of a basic setup that I might try out on the market. Ha
