Dust extraction – Part 4: Solid State Relay

In this part of the dust extraction build I will show the solid state relay that is used to drive the vacuum cleaner.

I could make this part of the project with a PCB with a triac and optoupler etc, but decided not to do this to save time. Instead I used an off the shelf SSR-40DA solid state relays.

During use this component will get hot, therefore I mounted it to the side of an aluminium enclosure. In this enclosure I also mounted a grommet for the power input, a grommet for the signal wire and a power socket for the output.
