@mrehorstdmd said in safety relay for ssr heated bed.:
How are you going to protect the protection relay from some crud preventing its armature from moving, or from the contacts welding shut?
My relay is noisy so I hear it clicking on each time I turn the printer on. Kind of a self test.
"perfect is the enemy of good" . 😉
It not a perfect solution but it reduces the risk of fire due to a short in the duet's mosfet or the SSR.
