Hi All

I’m upgrading my 3D printer to use a silicone heated mat to heat the bed. The mat runs off 240v mains.  
Are the SSR-40 DA relays available for core electronics suitable for this?

Hey Nigel,

They sure are! Check out Sparkfun’s video about them [here](https://www.sparkfun.com/videos#all/mmgrxLLx89U/254).
